Aggregate availability from multiple calendars
I prefer to keep personal appointments on one calendar (on Outlook.com) and work appointments on my work calendar (O365 Exchange), but Exchange only seems to use my work calendar to show my availability to other people in my organization. I'd like to have a way to aggregate my availability from multiple calendar sources, the way that you can overlay multiple calendars in Outlook. It's not really a matter of me seeing all my appointments, because I can easily see everything in a consolidated view in Outlook on my desktop or mobile; it's more about letting others in my organization know when I'm free to meet. I know there is (used to be?) a "free/busy server" option in Outlook client, but I feel like this should be something that can be set on my Exchange profile, so that it doesn't matter what client I'm using. Aside from that kind of option, I guess I'd guess I might be OK with a solution that duplicates anything added to my personal calendar as a block on my work calendar or vice versa, even if it's an IFTTT-type thing. I saw a similar post that mentions some 3rd-party tools from CodeTwo and Connecting Software, but given this is just a preference of mine, I'm probably not going to spend a lot on a workaround. TLDR: Is there a better approach to showing consolidated availability than manually duplicating my appointments between calendars? Thanks!Check out the new PST collection tool
Microsoft has released the successor of the PST Capture tool, named PST Collection tool. Apart from helping you with "collecting" PST files in your network, it can also "lock down" their usage. Details can be found in this article: https://support.office.com/en-us/article/Use-the-PST-Collection-tool-to-find-copy-and-delete-PST-files-in-your-organization-7a150c84-049c-4a9c-8c91-22355b35f2a7?ui=en-US&rs=en-US&ad=US#import And here's the downoad link: https://aka.ms/pstcollectiontoolBIMI Logos – Another Way to Stop Email Spoofing
Brand Indicators for Message Identification (BIMI) is a new industry effort to help identify email from reputable companies by displaying their logo alongside email (and potentially other items) in applications. https://office365itpros.com/2018/12/06/bimi-office365/Rebuild search index of a mailbox in Exchange Online
This was something new for me and couldn't find such a post here, so hereby I'm sharing the experience. One of our users showed me that there are some emails in her mailbox which can't be found by using search, nor in the Outlook 2013 rich client (in Online mode), neither in OWA. Tried to search for various texts and properties from those emails, but they was just 'invisible' for search. I've opened a case with the Office 365 support through the admin portal, and what they recommended was simply to run the following PS command: New-MoveRequest our_user@ourdomain.com It seems this, submitting a move request for that mailbox is the recommended way to force reindexing an ExO hosted mailbox. Once the move operation has completed (it takes a few hours depending on the mailbox size, progress can be checked with Get-MoveRequestStatistics) the mailbox got re-indexed, which fixed the search.Why has EOP ATP licensing been locked away?
When Advanced Threat Protection for EOP was released it could be purchased as an add-on service via the Office 365 admin portal. I added it to my own E3 tenant at one stage, before I later upgraded to E5. I'm currently working with a small business customer who could use the extra protection of ATP, particularly Safe Attachments. They are running Office 365 Business Premium. Neither they, nor any of my own prod or demo tenants, are able to purchase ATP as a standalone add-on today. I guess I found the reason, which doesn't sit well with me: https://technet.microsoft.com/en-us/library/mt148491(v=exchg.150).aspx "ATP is included in the E5 subscription. If you don’t have an E5 subscription, in order to begin using the safeguards provided by ATP technology along with your Exchange Online service, you need to purchase a separate subscription for ATP. You can order ATP through the Microsoft Online Subscription Program." What possible justification is there for limiting the customer's choice like this? It can't be to make things simpler - the "Purchase Services" page still lists 52 other items they can buy, some of which cost less than ATP did. So they need to either increase their costs by more than 2x to get ATP, or sign up to a VL agreement they don't want or need. Even if I can get them to accept the cost of E5 licenses by making use of other things that E5 includes, they don't want to move off Business Premium because they're excited about the new Microsoft Bookings app that is not available for E* tenants. Surely making it easier for customers to buy valuable services like ATP should be the priority here.

Incorrect processing of messages with multiple DKIM signatures?
Hello, I've been noticing strange behavior on our Exchange online where legitimately spoofed incoming messages that are double signed (Usually one unaligned DKIM signature for the sending infrastructure and one aligned for the RFC5322.From domain) are being falsely rejected by DMARC because exchange is using the unaligned signature for it's DMARC test. This is not limited to a specific From or MailFrom domain, I can find examples of this every day (large tenant, many subcompanies on one environment) and looks to me like a flaw in Exchange's implementation of the DMARC standard... According to the DMARC spec, this shouldn't be a problem: Note that a single email can contain multiple DKIM signatures, and it is considered to be a DMARC "pass" if any DKIM signature is aligned and verifies. (Source: RFC7489, Section 3.1.1) Kind regards, JordyExchange Professsional Career Profile: Adnan Rafique
