OUTLOOK Reverts to Classic every 24 hrs AVD
Hey All, I am looking for some support with AVD Windows 11 multi session... I have a series of inconsistences with user experiences. The major one is that Outlook (after upgrading to the new Outlook) reverts back to the Outlook Classic every day for users. Where did it go? why did it roll back - Here is the other issue is most of the users have to re authenticate every 24 hours with the Office 365 Apps, so after logging into AVD the are greeted with a message that there is something wrong with there work account and have to re authenticate and require to re-login Every day!

Below some recommendations for your situation:
Outlook Reverting to Classic Mode
- Check Default Settings: Ensure that the "New Outlook" is set as the default application for all users. Sometimes, group policies or user settings can revert to the older version.
- Profile Corruption: A corrupted user profile might cause Outlook to revert. Try creating a new user profile and see if the issue persists.
- Registry Settings: Verify registry settings related to Outlook. Incorrect configurations might lead to reversion.
- Update Outlook: Ensure that all users are running the latest version of Outlook. Updates often fix bugs and inconsistencies.
Reauthentication Every 24 Hours
- Session Lifetime Policies: Configure session lifetime policies in Microsoft Entra ID (formerly Azure AD). You can set sign-in frequency and persistent browser sessions to reduce reauthentication prompts.
- Conditional Access Policies: Use Conditional Access to enforce adaptive session lifetimes. This can help balance security and user convenience.
- Token Expiry: Check if token expiry settings are causing frequent reauthentication. Adjust these settings in the Microsoft Entra admin center.
- Network Issues: Ensure that there are no network interruptions or proxy settings that might be causing authentication failures.
The CA rule I made had no affect on the sign on -- it just made it worse because now the test users need to sign in on the their devices [outside of AVD] once a week...so this is being rolled back - I messed around with enabling the office container... for myself now I can reproduce the outlook roll back every sign out and sign in...i am at a loss...
Thanks for posting a comment... For Outlook issue - I myself had not had the roll back happen for me until now...today i login and it is gone. The Default App settings was left with a Outlook now a (Blank icon) I reinstalled and the icon returned in the defaults apps...so it was selected...Update outlook? - there is no spot to update outlook (new) as this just happens automagically now - no control... Registry setting i am reviewing, if there is anything i should be targeting i would love the suggestions. Profile corruption...i am gonna rule this out or not pursue this just yet - because it is happening to way to many new users plus. and there is no indication in Event Logs to suggest this. The reauthentication issue - i have setup a CA rule to see if that helps - this may also help with another Dynamics Sales (CRM) issue with have with every 24 hours requiring a login...so thanks for that...
