Outlook Calendar Groups Malfunctioning
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".
- File
- Account Settings
- Account Settings (Again)
- Email Tab
- Double Click Your Email In The List
- More Settings
- Advanced
- Uncheck "Turn on shared calendar improvements" Under "Microsoft 365 Features"
- Click Apply
- Click OK
- Exit Outlook Entirely
- 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.
Henric Appelgren Actually yes, I repaired my installation of Outlook and it fixed the issue! It looks like Microsoft made an update that was confusing me as well - it makes it so that you can't add the same calendar to two different calendar groups, which is a bummer. But the reparation of the Outlook installation did the trick!
AlyssaL036 I'm having a similar issue after receiving enterprise Outlook updates. I'm wondering if the calendar groups that were malfunctioning for you were (1) shared calendars (e.g., you are or have a delegate, or you utilize a shared mailbox); (2) calendars that are tied to a M365 group; or (3) were groups you made in your personal calendar and added individuals' names to (i.e., NOT tied to an M365 group)? Thanks so much!
