Known Issue: Outlook search does not return results after upgrade to Windows 11

After upgrading to Windows 11, Outlook searches may return no result.

Turned-Off Basic Authentication – All Protocols

We are making some changes to improve the security of your tenant. We announced in 2019 we would be retiring Basic Authentication for legacy protocols and in early 2021 we announced we would begin to retire Basic Authentication for protocols not being used in tenants. You can always read the latest information about our plans to turn off Basic Authentication here .

Today we turned off Basic Authentication for POP3, IMAP4, Remote PowerShell, Exchange Web Services, Offline Address Book, MAPI, RPC, SMTP AUTH and Exchange ActiveSync protocol in your tenant.

Send As Group by Default

Microsoft 365 Groups in Outlook currently supports “Send As” functionality which enables group members to Send As a group (“From” address has group id) rather than as an individual. Group members should have this permission configured for the specific Groups by admins to make use of Send As capability. For the groups where user has Send As permissions enabled, user has the option to pick the groups account in the “From” address. Today, by default, the email loads up with individual email id in the From field when user compose, reply, reply all and forward messaged form group mailbox.

With this change, for users having the “Send As” permission for specific Microsoft 365 groups, when they compose, reply, reply all and forward mail from Groups mailbox then the default “From” address populated would be Group id instead of their individual id. This change will affect only when users are inside a group mailbox where they have Send As permissions. There will be no changes in behaviors in the personal/individual mailbox.

User experience update for Explorer and Real-Time Detections: Default All Email view and more updates

We are updating the user experience for Explorer and Real time detections, to improve the hunting experience and workflows, as well as align with modern accessibility standards . These are experience updates and do not involve major functional changes for core experiences like filtering, export and saving queries.

NOTE: For a short while, as we roll out updates, you will be able to toggle between the old experience and new experience. Note that toggling would impact only your session and does not impact anybody else within your tenant.

Anti-malware policy : Common attachment filter : Additional file types block by default

The ‘Common attachment filter’ option in the ‘Anti-malware’ policy helps the Administrator configure the file types (based on file extension) which need to be blocked in the emails. This block action is applied anytime the file type of any attachment in the email matches this configurated file type list.

The current pre-configured list has 96 file types. Of these 96 file types, 10 files types are selected by default in the block list. When a new policy is created, these 10 file types are selected, to be blocked, by default. Administrator can make changes to this selection by selecting more file types or making changes to existing file types. If the Administrator chooses to extend this behavior to more file types, then this is possible using PowerShell option.
