Mac Office Licensing Issue
If you are unable to edit files in Office (Word, Powerpoint, Excel, etc) or there is pop asking to "activate windows", please try the following:
Make sure that all Microsoft apps (Word, PowerPoint, Teams, etc.) are closed by pressing CTRL and selecting "quit".
Click on your desktop or open a Finder window, then click on the “Go” menu at the top of your screen.
Select “Go to Folder” and enter “~/Library/Group Containers/” and press Return.
This will open a new Finder window. If any of the following folders appear in this folder (or any other folders that start with UBF8T346G9 or similar), move each of them to the trash:
UBF8T346G9.ms
UBF8T346G9.Office
UBF8T346G9.OfficeOsfWebHost
UBF8T346G9.com.microsoft.oneauth
UBF8T346G9.OfficeOneDriveSyncIntegration
Once deleted, restart your device, and re-open Microsoft
