Hi Kevin Clarke
Thank you for reaching out to Microsoft Q&A Forum and sharing your experience.
I appreciate you confirming that you’ve already restarted, updated, and reinstalled OneNote, and that there has been no change.
I’ve tested OneNote for Mac version 16.105.2 on my own macOS environment and wasn’t able to reproduce this behavior. In my testing, the Create New Tag option worked as expected. Since the issue persists after reinstalling, this suggests it may be related to a specific user profile, notebook, or local configuration rather than the app installation itself.
If you haven’t already, you could try the following checks to help isolate the cause:
- Sign out of OneNote, then sign back in and test again
- Test in a new or different notebook
- Test using a new macOS user profile, then sign in to OneNote and check whether the issue occurs there as well
If none of the above changes the behavior, one remaining step is to reset OneNote’s local container to clear cached data and preferences:
- Close OneNote completely
- In Finder, press Command + Shift + G and enter
~/Library/Containers - Locate Microsoft OneNote (or
com.microsoft.onenote) - Move the folder to your Desktop as a backup
- Reopen OneNote and sign in again
As a workaround, since you’ve confirmed that version 16.99 works correctly, you may choose to continue using that version for now. To help maintain stability, you might also consider temporarily disabling automatic updates to prevent the app from upgrading again until this behavior is better understood.
