Hello!   I’ve been having an issue with Outlook’s calendar groups since November 5th of this year. I believe the issue started almost immediately after Outlook went through a larger update (the one...

    I'll save anyone reading this thread some time - these are the two solutions that have worked for people:

    For me, it worked to repair my Outlook installation:

    It seems people have misunderstood my original solution. I did not "re-install" Outlook, I "repaired my installation" of Outlook. Those are two different things. I haven't had the issue since then. See this link to learn how to repair the installation: https://www.slipstick.com/tutorial/repair-office-outlook-installation/#:~:text=The%20steps%20are%20basically%20the%20same%20for%20all,the%20desired%20repair%20option%20and%20complete%20the%20wizard

    For others, it worked to uncheck "Turn on shared calendar improvements".

    1. File
    2. Account Settings
    3. Account Settings (Again)
    4. Email Tab
    5. Double Click Your Email In The List
    6. More Settings
    7. Advanced
    8. Uncheck "Turn on shared calendar improvements" Under "Microsoft 365 Features"
    9. Click Apply
    10. Click OK
    11. Exit Outlook Entirely
    12. Restart Outlook

    If it doesn't work after these steps, restart your computer and then check again before assuming this step hasn't worked. If another solution is found, I will edit this comment with that solution.

    Ureka. This setting solved the issue. Unchecked these improvements and the calendar groups can be used again with multiple calendars in different calendar groups! Thank you KunpengCaiKC!

    Hi KC,
    I think Alyssa already solved her problem by reinstalling Office.
    For us, unfortunately, neither reinstalling or disabling "Calendar Improvements" worked.

    Best regards

      Our experience is the same as MartinHolstDk. Uninstalling/reinstalling Office/Microsoft 365 doesn't resolve the issue. Enabling/disabling shared calendar improvements also offers no resolution.

      MartinHolstDk, thanks for sharing the Outlook.exe/ResetSharedFolders "solution." Until Microsoft changes the functionality in OWA to allow an individual calendar to be added to multiple calendar groups, I suspect I'm going to have to document a work around solution for our admin assistants that will still require cleaning up calendar groups. If you get a resolution from Microsoft, please let us know. Thanks!
