Recurring Meeting Requests with Conflicting Instances 2: The Power of Delegates
The key takeaway from my last post on this topic was that the Resource Booking Assistant never allows double booking of a resource room calendar as a result of a recurring meeting request (please see Automatic Processing of Recurring Meeting Requests with Conflicting Instances). Since there are times that an administrator may want to allow double-booking, we offered two workarounds that I’d like to address in a bit more depth. I'd also like to offer a third one that wasn’t mentioned before: 1) Send Follow-Up Nonrecurring Meeting Requests to Double Book Recall that if a recurring meeting series is accepted individual conflict notifications will be emailed to the organizer in addition to the acceptance email for the series. The organizer can use those declined-instance emails as a reference for following the first of our workarounds, which would be to send additional non-recurring meeting requests to double-book the intended resource room for each declined instance. This method, though laborious, allows fine control over when a resource is double booked and when not. Suppose on the other hand an administrator follows the second workaround, and hands control to a trusted delegate instead of the Resource Booking Assistant? A delegate has the human discretion to allow all recurring meeting conflicts to double book by accepting an entire recurring meeting series. It also turns out a delegate can selectively decline any number of conflicting instances while accepting the series, something the assistant cannot. The question came up about how exactly they can do this, so let’s take a look: 2) Allow a Delegate to Double Book Resources The request policy on a resource mailbox can be configured to require delegate control over resolving recurring meeting request instance conflicts. But how exactly do they use that power? What might the process look like, and what tools can they use carry it out? The best functionality for this is in Outlook 2010. Let’s go to an example. Say we have a resource room, called Green Room, which is managed by a delegate named Howard. As meeting requests for the Green Room come in Howard accepts them for the room calendar. Presently there’s a meeting scheduled for 2PM on Wednesday, and another for 3PM on the following Thursday. Now a new recurring meeting request with the Green Room as the room resource goes out to several recipients. The room’s request policy requires Howard to approve all meeting requests, so this new one gets forwarded to him. We see that the recurring meeting request is for four instances, Tuesday through Thursday, from 2:30PM - 3:30PM each day. Outlook helpfully points out (highlighted in yellow and also below the Calendar Preview) that two of the four instances conflict with the existing appointments: If Howard wishes to accept the entire series, and allow double booking he can just accept the whole thing. But what if he wants to decline one conflict, but allow the other? Howard can click on the arrow next to “Conflicts: 2” and get a preview of each area of the calendar where conflicts overlap with an existing appointment. He does so, and sees the first conflict is with the Wednesday, 2PM Catalog Review meeting: The second is with the Sales Presentation meeting on Thursday: Suppose Howard wishes to decline the double booking on Thursday, but let the Wednesday conflict get booked? To decline the Thursday instance he can simply double-click on the item in the Calendar Preview section of the forwarded meeting request. That action will open up a view for that time from the Green Room’s calendar. Howard can then right click on the instance that he wishes to decline, go to the Decline menu item, then select an option to decline just this occurrence: Now that Howard has determined which instance to decline and which to allow he can simply go back to the original forwarded meeting request, and accept the series. This will accept all the remaining instances while preserving the manually declined instances: So to summarize a delegate's power in this area, they can use the conflict notifications provided in Outlook 2010 to quickly decline (or accept) individual occurrences of a recurring meeting request. 3) Send a Series Update Without Changing Details There is a third known way of working around the Resource Booking Assistant’s refusal to double book a room due to a recurring meeting request. Thanks to feedback from a customer relayed to me by my colleague Patriciu Seliceanu, we now know that a meeting organizer can simply send an update for a recurring meeting but without changing any details. The amazing result is that conflict instances declined before are then accepted. This workaround of course requires that conflicts be allowed for single-instance meeting requests, which by default is enabled in virtue of the AllowConflicts attribute set to "True" for calendar processing settings. The update to the recurring meeting works because each recipient receives not another recurring meeting request, but an update meeting request (with no actual changes) for each individual instance. Since Exchange sees much the same as the single-instance meeting requests from workaround method 1 above it allows double-booking for each updated instance. This may save a bit of labor over the steps required in item 1 of this list, such as when the number of conflicts is high, and assuming every conflict should be double booked. In conclusion, there are a number of ways to work around the safety mechanism inherent in the Resource Booking Assistant which prevents recurring meeting request from double-booking a resource mailbox. The most robust and powerful of these is the intrepid delegate with Outlook 2010 at their fingertips and Exchange 2010 at the ready. Please note though that for the majority of cases, you should not even have to worry about doing this, as in most cases, the default behavior is the correct one. Thanks to Tom Kern for his help and counsel, and to Patriciu Seliceanu for method 3. Jesse TedoffCalCheck - The Outlook Calendar Checking Tool
Over the past year or so I have been working on this tool - adding functionality and checks based off my experience as an Outlook engineer, and from suggestions given by other engineers. Well, this February the tool has been released so that all our customers can download and use it to check for potential problems in their calendars - which will hopefully be a real time saver when you encounter a problem with your Outlook Calendar - or with a user’s Outlook Calendar in your organization. Installation Download CalCheck from the Microsoft Download Center. Documentation: Information about the Calendar Checking Tool for Outlook (CalCheck) - Outlook | Microsoft Learn. Important: The 64-bit version of this tool is only for use with the 64-bit version of Microsoft Outlook 2010. The download is a ZIP file - just unzip it in an empty directory, open a command window in that directory, and run it. What CalCheck does The Calendar Checking Tool for Outlook (CalCheck) is a command-line program that checks Microsoft Outlook Calendars for problems. The tool opens an Outlook profile to access the Outlook Calendar. It performs various checks, such as permissions, free/busy publishing, delegate configuration, and automatic booking. Then each item in the calendar folder is checked for known problems that can cause unexpected behavior, such as meetings that appear to be missing. As CalCheck goes through this process, it generates a report that can be used to help diagnose problem items or identify trends. Checks performed The following Calendar-specific checks are performed and logged in the report: Permissions on the Calendar Delegates on the Calendar Free/Busy publishing information Direct Booking settings for the Mailbox or Calendar Total number of items in the Calendar folder The following item-level checks are performed and logged in the report: No Organizer email address No Sender email address No dispidRecurring property (causes an item to not show in the Day/Week/Month view) Time existence of the dispidApptStartWhole and dispidApptEndWhole properties No Subject for meetings that occur in the the future or for recurring meetings (a warning is logged) Message Class check (a warning is logged) dispidApptRecur (recurrence blob) is checked for time on overall start and end times, not for exceptions Check for Conflict items in the Calendar Check for duplicate items, based on certain MAPI properties Check if over 1250 recurring meetings (a warning is logged) and 1300 recurring meetings (an error is reported); 1300 is the limit Check if you are an attendee and you became the Organizer of a meeting Check meeting exception data to ensure it is the correct size Server Mode You also have the option to run CalCheck in Server Mode. In Server Mode, CalCheck attempts to open all mailboxes on the Exchange server and perform the checks listed in the "Checks Performed" section of this article. Server Mode generates a CalCheckSvr.log file, which lists the mailboxes that have errors. Additionally, CalCheck generates a separate CalCheck__.log file for each mailbox. This log file shows more mailbox-specific detail. To use Server Mode, you must use a messaging profile associated with an account that has permissions to all of the mailboxes on the specified Exchange server. To run server mode, use the “-S” command-line switch. Example Running to check a single mailbox/calendar: If you don’t specify a profile on the command line - then you will be prompted to choose a profile as in the above screenshot. Once you have chosen your profile - the tool will run - and you will see similar output as long as everything is successful: Looking at this window shows you that there is a CalCheck.log, and where to go and find it. Opening that will show some info like the following: 02/17/2012 05:09:20PM Calendar Checking Tool - Version 1.0 02/17/2012 05:09:20PM ==================================== 02/17/2012 05:13:45PM Opening mailbox: Mailbox 02/17/2012 05:13:45PM /O=Org/OU=OU/cn=Recipients/cn=Mailbox 02/17/2012 05:13:45PM Local time zone: Eastern Standard Time 02/17/2012 05:13:45PM Successfully opened the Calendar folder. 02/17/2012 05:13:45PM Processing calendar for Mailbox 02/17/2012 05:13:46PM Successfully located and opened the local free busy message for this mailbox. 02/17/2012 05:13:47PM Publishing 2 month(s) of free/busy data on the server. 02/17/2012 05:13:47PM Resource Scheduling / Automatically accept meeting requests is disabled. 02/17/2012 05:13:47PM ==================================== 02/17/2012 05:13:47PM Delegates for this mailbox: 02/17/2012 05:13:47PM =========================== 02/17/2012 05:13:47PM No delegates are set. 02/17/2012 05:13:47PM =========================== 02/17/2012 05:13:47PM Permissions on this Calendar: 02/17/2012 05:13:47PM ============================= 02/17/2012 05:13:47PM Default: None 02/17/2012 05:13:47PM Manager: Reviewer 02/17/2012 05:13:47PM Coworker1: None 02/17/2012 05:13:47PM Coworker2: Reviewer 02/17/2012 05:13:47PM Coworker3: Reviewer 02/17/2012 05:13:47PM ============================= 02/17/2012 05:13:48PM Found 1404 items in the Calendar.

Print this message Some additional tips about specific switches: “-M” You must use the legacyExchangeDN for the mailbox, and the profile you use must be for a mailbox that has permission to open that other mailbox. “-A” Will create a CSV file that includes all calendar items - one in each row. There will be several properties listed for each item that can be used to look for problems not detected by the tool: You can view all items in the Calendar by opening the CSV in Excel. You can sort and filter items based on things like start time, subject, recurring items, etc. This can be useful for finding problems that can’t be detected by CalCheck, or that currently aren’t looked for by CalCheck. If you find a problem item in the CSV, you can open the Calendar and put it into Category view to get a similar view of the Calendar in Outlook. To do this, in Outlook click the View tab, click the Change View drop down, and choose By Category. This will give a view of the Calendar like the following: This view shows all the items in the Calendar as a list - similar to looking at emails in the Inbox folder. You can sort on things here like Subject, Location, Start, and End. This can be used to find the problem item in the Calendar folder when it is difficult or impossible to find in the normal Calendar view. “-F” Will create a CalCheck folder in your folder list, and will move items marked as an Error to that folder: Items can easily be moved back to the Calendar, or can be deleted from here if not needed, or corrected if possible and then placed back in the Calendar. The general rule of thumb would be to recreate the item and delete the item that was moved out to the CalCheck folder. “-R” Will create a mail message in the Inbox folder with the CalCheck.log file attached to it. This is useful when running the tool in Server mode - as each user will get their report in their Inbox: “-No” There are two of these: “-No org” and “-No dup”: The “-No org” will omit the check for the “attendee becomes the organizer of the meeting” check. Part of this check uses the legacyExchangeDN of the mailbox. If the legacyExchangeDN has changed for any reason - like a migration - then this test will give errors for items that may not really be in error. The error that is logged by CalCheck will show both DNs. Here is an example: 12/21/2011 05:27:25PM ERROR: dispidApptStateFlags is 1, but the address for this mailbox does not match the organizer address. 12/21/2011 05:27:25PM Check to ensure the Organizer Address is correct, and whether or not this user should be the organizer. 12/21/2011 05:27:25PM Organizer Address: /o=Org1/ou=admin group 1/cn=recipients/cn=user1 12/21/2011 05:27:25PM DN for this user: /o=Org2/ou=admin group 2/cn=recipients/cn=user1 12/21/2011 05:27:25PM See KB 2563324 for additional information: http://support.microsoft.com/default.aspx?scid=kb;EN-US;2563324 12/21/2011 05:27:25PM Properties to help investigate this reported item: 12/21/2011 05:27:25PM Subject: Test The mailbox here is the same actual mailbox - but because the legacyExchangeDN changed - it is marked as an error. The “-No dup” will omit the duplicate item detection - as this test creates an in-memory list of items and tests each item against that list. This can slow the process down a bit due to the extra processing and memory usage. What CalCheck does not do CalCheck is a reporting tool only. It will not automatically modify or “fix” any items. It will move items detected as error items to the CalCheck folder if the “-F” switch is used, but otherwise no changes will be made to any items. CalCheck only works against Calendars located on an Exchange server. It will not work against other servers, such as IMAP or POP3, etc. CalCheck can’t find every kind of corruption that can possibly happen to a Calendar item. However - it can find many known problems that can be knocked out without having to spend time combing through a Calendar and/or contacting a help desk.

Microsoft recently announced the General Availability of High Volume Email for Microsoft 365, also known as HVE, in Exchange Online. This is an important and long-awaited capability for organizations that need to send large volumes of internal email from applications, devices, or line-of-business systems without using regular user mailboxes as bulk-sending engines. But HVE should not be misunderstood. It does not mean that every mailbox in Exchange Online should now be used for mass email. It does not mean Exchange Online has become a general-purpose marketing platform. And it does not remove the need for proper outbound email governance. Why HVE Matters For years, many organizations have used regular Exchange Online mailboxes, shared mailboxes, or service accounts to send automated messages from applications, scanners, monitoring platforms, ticketing platforms, and custom business applications. That approach creates several problems. Standard mailboxes are designed for human and business communication, not for sustained high-volume automated traffic. Exchange Online has recipient limits, message rate limits, outbound spam protections, and tenant-level controls to protect the service and reduce abuse. HVE introduces a more appropriate model for specific high-volume scenarios. Instead of using a normal mailbox for automated traffic, organizations can create dedicated HVE accounts and use specific SMTP endpoints, admin controls, reporting, and governance for approved high-volume internal messaging scenarios. What HVE Is Designed For HVE is designed for automated, operational, and transactional messaging at scale, primarily for internal recipients within the tenant. Examples include: Internal application notifications. Line-of-business system messages. Device-generated messages. Operational alerts. Security advisories. Internal workflow communications. Monitoring platform alerts. IT service notifications. Large-scale internal announcements generated by systems. This is especially relevant when the organization needs to send messages at scale but still wants to keep the workload within Microsoft 365 governance and Exchange Online mail flow. In practical terms, HVE is useful when the sender is not a human user, but a controlled business system. What HVE Is Not HVE is not a replacement for marketing platforms. HVE is not a general-purpose internet bulk email engine. HVE is not a way to bypass Exchange Online sending limits for external campaigns. HVE is not the correct platform for newsletters, promotional campaigns, large-scale customer communication, or high-volume external transactional email. For external transactional, marketing, or customer-facing bulk email, organizations should evaluate platforms designed for that purpose, such as Azure Communication Services Email, SendGrid, Amazon SES, Mailchimp, Brevo, or another specialized delivery platform. When to Use HVE Use HVE when the workload matches these characteristics: The sender is an application, device, service, or business system. The recipients are primarily internal users in the Microsoft 365 tenant. The volume is higher than what should be sent from a standard mailbox. The workload is operational, automated, or transactional. The organization needs centralized Microsoft 365 administration and reporting. The organization wants to avoid impacting user mailbox sending limits. The use case is approved, documented, monitored, and governed. Good examples: A security platform sending internal security advisories. A monitoring system sending infrastructure alerts to internal teams. A business workflow system sending high-volume approval or status notifications. An IT service platform sending internal notifications. A service management platform sending ticket updates to internal users. A device management system sending operational messages to internal teams. When Not to Use HVE Do not use HVE when the workload is external bulk email. Avoid HVE for: Marketing campaigns. Newsletters to customers. Promotional email. Mass external invitations. External transactional email at scale. Customer invoices and receipts in high volume. OTP or password reset flows for external users. External portal notifications. Any workload where deliverability, bounce handling, reputation management, unsubscribe handling, analytics, or customer consent management are required. Those workloads require a platform designed for external delivery, reputation management, suppression lists, opt-out, tracking, bounce handling, and compliance. Who Should Be Allowed to Use HVE HVE should not be enabled casually for every team or every application. It should be treated as a controlled platform capability. Recommended eligible senders: Approved line-of-business applications. Corporate systems owned by IT, Security, Operations, Facilities, or Service Management teams. Managed devices or services with a clear business purpose. Internal platforms that send operational messages to employees. Applications with documented ownership, authentication, monitoring, and expected volume. Recommended non-eligible senders: Normal users. Shared mailboxes used by humans. Marketing teams sending to external audiences. Unmanaged scripts. Legacy systems with no owner. Applications with unknown volume. Systems that send to external recipients at scale. Any application using HVE just to avoid standard mailbox limits. The core principle is simple: HVE should be enabled for workloads, not for convenience. Governance Model Before enabling HVE, organizations should define a governance model. At minimum, each HVE account should have: A named business owner. A technical owner. A documented purpose. Expected daily and monthly volume. Recipient scope. Authentication method. Monitoring process. Incident response path. Decommissioning criteria. Review frequency. HVE accounts should not become invisible service accounts that nobody owns. They should be treated as privileged communication identities. Security and Authentication HVE supports OAuth authentication, and Microsoft provides guidance for restricting OAuth authentication to specific Microsoft Entra ID applications. This is important because organizations should avoid broad, uncontrolled access. They should restrict which applications can send through each HVE account, monitor usage, and separate workloads by purpose. For example: One HVE account for security alerts. One HVE account for monitoring systems. One HVE account for IT service notifications. One HVE account for internal operational communications. This separation improves visibility, investigation, accountability, and risk containment. HVE vs Standard Exchange Online Mailboxes A standard Exchange Online mailbox should be used for normal human communication. A shared mailbox should be used for collaborative business processes. An HVE account should be used for approved high-volume internal system email. A dedicated external delivery platform should be used for marketing, bulk external communication, or high-volume transactional email. Scenario Recommended Platform Human business email Exchange Online mailbox Team or department mailbox Shared mailbox Low-volume application notifications Standard Exchange Online, if approved High-volume internal system notifications HVE Internal operational alerts at scale HVE Marketing campaigns Marketing platform External transactional email Transactional email service Customer newsletters Marketing automation platform OTP/password reset for external users Dedicated transactional platform External bulk email Dedicated bulk email provider HVE and the Mailbox External Recipient Rate Limit Cancellation Microsoft also announced that the Mailbox External Recipient Rate Limit in Exchange Online was cancelled indefinitely. However, that cancellation should not be interpreted as permission to use Exchange Online for uncontrolled bulk sending. Microsoft was clear that other limits remain unchanged, including the existing Recipient Rate Limit and the Tenant-level External Recipient Rate Limit. That distinction is important. The cancellation of one mailbox-level external recipient limit does not remove the need for proper architecture. Exchange Online still has service limits. Outbound spam controls still apply. Tenant-level protections still matter. And HVE is still not a marketing engine. Practical Architecture Decision Before enabling HVE, ask these questions: Who is sending? Is the sender a human, shared mailbox, application, or device? Who are the recipients? Are they internal or external? What is the expected volume? Is the workload operational, transactional, promotional, or human communication? Does the business need Microsoft 365 mail flow and governance? Does the use case require bounce handling, unsubscribe, tracking, or reputation management? Is the application properly authenticated and monitored? Who owns the account? Who approves the sending pattern? Who responds if the account is abused? If the workload is internal, automated, high-volume, and business-approved, HVE may be the right answer. If the workload is external, promotional, customer-facing, or marketing-driven, use a dedicated email delivery platform. Recommended Enablement Approach Organizations should enable HVE in phases. First, identify existing systems currently using user mailboxes, shared mailboxes, or SMTP AUTH for automated sending. Second, classify each workload as internal, external, operational, transactional, marketing, or human communication. Third, migrate only approved internal high-volume workloads to HVE. Fourth, move external high-volume workloads to dedicated email delivery platforms. Fifth, monitor usage and review HVE accounts regularly. This avoids turning HVE into another uncontrolled sending layer. Conclusion High Volume Email for Microsoft 365 is an important addition to Exchange Online. It gives organizations a native way to support high-volume internal system messaging without using standard mailboxes for automated high-volume traffic. But HVE is not a free pass for bulk email. It is not a marketing platform. It is not a replacement for transactional email services. And it should not be enabled for every mailbox or every application. The right approach is workload classification. Use Exchange Online for corporate communication. Use HVE for approved high-volume internal system messaging. Use dedicated platforms for external bulk, marketing, and transactional email. The question is not only: “Can this system send email through Microsoft 365?” The better architectural question is: “What type of email is this, who is the audience, and what is the correct platform for this workload?” That is where proper email architecture begins.Import Bulk PST to Office 365 Step by Step | Stellar Migrator for Outlook

Gmail to Microsoft 365 Migration Issue Open for 7+ Days – Seeking Guidance or Escalation Path
I’m facing an issue with a Gmail to Microsoft 365 migration that has been open for more than 7 days, and I’m looking for guidance or an escalation path from the community. Scenario: Migration type: Gmail to Microsoft 365 Issue started: April 22 Current status: Stuck with no clear resolution What’s happening: The support ticket has been active since April 22. However, the updates I’ve been receiving are generic responses such as “we are working on it” and “this has been prioritized.” Despite multiple follow-ups, there has been: No clear root cause identified No ETA provided No technical breakdown of the issue I also requested a callback from the assigned manager and technical lead to better understand the situation, but the communication has remained email-only with repeated status updates. What I’m looking for: Has anyone faced similar issues during Gmail → Microsoft 365 migrations? Are there known blockers or common causes that could lead to this kind of delay? What is the recommended escalation path when support is unable to provide technical clarity or ETA? Any insights, workarounds, or guidance would be highly appreciated. Thank you in advance.
