Exchange 2019 - Exchange SE - In-Place upgrade
Hello, we’re currently running an Exchange Server 2019 hybrid environment (DAG on-prem + Exchange Online) with a few on-prem user mailboxes used for automated system communications (SMTP) - the mailboxes are not being used in Outlook. We migrated from Exchange 2016 to Exchange 2019, using a trial installation of Exchange 2019, which has expired. We are planning to upgrade to Exchange Server Subscription Edition (SE) and want to ensure the following is supported: - Can we perform an in-place upgrade from the expired Exchange 2019 trial to Exchange Server SE, or do we need to relicense/reactivate Exchange 2019 first? - What is the right / best action plan for us in this case Kindest Regards Leon
How to Send-As a Distribution Group (via SSIS ScriptTask) via Exchange Online using Modern Auth?
We have a SQL Server Integration Services (SSIS) task that retrieves emails from a table in our Customer Relationship Management (CRM) system. The emails contain From:, To:, Cc, and Bcc: addresses, in addition to the body and other data. The SSIS task then reads the data, connects to a local on-premises Exchange 2016 server to send the emails, and allows the SQL Server IP address to log in anonymously and send emails as any user in the From field, provided the address is valid on the Exchange server. We are considering removing the local on-premises Exchange 2016 server and need to modify the SSIS task to connect to Exchange Online to send the emails. We are exploring the use of Modern Authentication, App Registration, and Microsoft Graph to send the emails. The From addresses in the CRM can be an address of a User Mailbox, Shared Mailbox, or Distribution Group. Based on my research, it appears there is no way to send emails as a Distribution Group via Microsoft Graph. Therefore, I am forced to use SmtpClient and logging in as a user with Send-As permissions on all of the groups, which has its own drawbacks. What is the proper way to programmatically send as a Distribution Group? We have about 40 Groups we send as.
Exchange Mailbox copy Databases Keep Disconnect
Hello, Since June 26th, PRTG has been notifying me about the disconnection of the copy databases on the secondary Exchange server. Each time, I receive an alert about one of the copy databases hosted on the secondary Exchange server, and it comes back online in less than 5 minutes. Everything is working fine on the primary Exchange server, and the mounted databases on the secondary server are also functioning properly. Only the copy databases on the secondary Exchange server keep disconnecting and go back online in less than 5 minutes.
Recurring booking issues // 'AutomateProcessing' enabled on delegate approval
Having issues with our 9 rooms just behaving terribly - bookings just do not sync between different users. Have tried wiping and rebuilding the permissions. Still having issues. Have tried using Exchange AC's built in 'Resource Booking' report - this actually does not show me any bookings for the last three days. Have tried using the AC's 'Calendar Logs' report, which gives me the following output for a specific booking. Things I notice: 1) a lot of 'Not Found' params and 'InvalidSchemaPropertyName' params. 2) The timestamps are all in UTC, despite us being AST. I'm not sure if either of these have anything to do with bookings not sync'ing between users or not. CoPilot has suggested they may be influencing things - and you'd think in that case you'd be able to edit them without powershell, but.. CoPilot pulls from Microsoft docs. . Below is the output from the 'Calendar Logs' report - I can't really make sense of it. This was originally made in the web client, then checked on Outlook - I'm not sure how these relate, or if there's even a way to check this?

The spreadsheet is attached tho I've used the following cmdlets in PowerShell to dig into this issue - Get-CalendarProcessing, Get-MailboxFolderPermissions, Get-MailboxRegionalConfig. These are setup with 2 delegate editors (as in, people who approve/decline meeting invites) and 6 editors (people who can book without needing approval, and do not have the Delegate flag. All 8 have SendAs permission, so bookings dont just show under their name.. Weirdly, these rooms look to have AutomateProcessing set to AutoAccept, despite very clearly being configured not to do this in EAC. THIS article of course does not mention the AutomateProcessing param except for in 3 examples - one of which is a delegation scenario where logically, automate processing would be off.

The Exchange Extended Security Update program is a 6-month lifeline for organizations struggling to upgrade servers to Exchange Server SE. Although it’s easy to upgrade a server to , many things might get in the way before the Setup program can run. Small things like vacations, buying new hardware, or deploying a new O/S. From August 1, organizations can sign up to receive security updates from October 2025 to April 2026. https://office365itpros.com/2025/07/17/exchange-extended-security-update/

A July 15 announcement says that Exchange Online is reducing the Delicensing Resiliency threshold from 10,000 to 5,000 mailboxes. That’s fine, but this feature should be available for all Exchange Online tenants. It’s a sticking plaster for how group-based licensing works and is inconsistent with how OneDrive for Business deals with unlicensed personal user data. https://office365itpros.com/2025/07/16/delicensing-resiliency-5000/High Volume Email Account and Conditional Access
Hi all, We've set up a HVE account, and set up a Conditional Access Policy targeting this account to block sign-in to all cloud apps for any location except for the excluded IP address ranges. A couple of problems: 1. I can still authenticate and send from an IP address not in the excluded range. 2. I don't see any sign-in logs on Entra ID under this account. Has anyone been successful securing the HVE account with conditional access please? I've tested with a physical scanner and also 'Send-MailMessage' using powershell - none of the authentications are logged in Entra ID.
