Until this morning I've been happily using categories: created my own, assign and change them regularly. Suddenly under Categorize I can't assign categories. The only option is to edit categories (which works) but can't assign to email nor calendar entries. Help please. When I do go to Edit Categories, it shows my account as IMAP -- but it is NOT, it is POP.

I am having the same issue after updating Outlook. This appears to be a bug that was introduced in the update. When can we expect Microsoft to fix this? Being unable to use categories is a huge problem for my workflows.

Same for me. With categories the Calendar function becomes much less robust and forces consideration of alternatives (i.e. gmail).

I use MSO 16 for Mac. There is no option to to reset MSO 365 in MSAU!

Hi Amy, the same thing happened with categories for me too today, just after I updated my Mac to macos Tahoe version 26.1. and I can't resolve it either!

Can you address issue for IMAP users also?
Also when I go into edit categories they are all there as previously, but just don't show to be selected.

This a crucial feature for my business and one of the main reasons I use outlook over the MAC calendar. Time to ditch Microsoft?

Same issue, has this not been resolved yet ?
I did nothing about this issue and the update to 16.103.2 (25112216) three days ago fixed the problem!
Well done to us for flagging it (hahah)
The rollback workaround as posted above from Amy U works! (Thank you).
For MacBook users be sure to delete Outlook.app (step 3) or the fix won't work. Here's the link for previous updates: https://learn.microsoft.com/en-us/officeupdates/update-history-office-for-mac

Děkuji, funguje perfektně a moc díky i za odkaz. :-) konečně mám zpět kategorie.
This worked for me and solved the problem.
But it's not really a long-term solution is it? Unless you never want to update Outlook again. Logical that if an update renders something useless, removing update should restore functionality. Perhaps I'm seeing it too simplistically - but I want updates AND categories. Crazy?

It didn't work for me. This is intensely frustrating. I didn't want or need anything more than the legacy version was already providing me. The new version has caused endless frustration and pointlessly wasted more hours than I can count.

I noticed that my Outlook Legacy application was updated at 9pm Wed night. Thursday morning, I no longer could categorize emails or events on my calendar. I have a POP account. AI stated "If categories in Outlook stopped working, first check your email account type to ensure it's Exchange or Office 365, as IMAP accounts do not support categories. Next, try creating a new item to see if categories work, and check for Outlook updates. If the issue persists, clear the Outlook cache, reset your view settings, or create a new Outlook profile. "
I think that the most recent autoupdate requires an Exchange or Office 365 account. What a bummer.

My problem occurred when I updated Outlook after the Mac update to Tahoe 26. Microsoft told me the Outlook update was not compatible with Tahoe … yet it’s Outlook for Mac?!
As noted above, this is FIXED in the current Outlook update.
