Hi @Emmett K ,
Does it prompt "You need to activate Office for Mac within XX days"? If so, please try the following steps to check this issue.
- Download and run the License Removal Tool.
- In Spotlight Search (the magnifying glass) on your Mac, search for and open Keychain Access to delete the following files:
(Note: You will need local admin privileges to make changes to your Keychain Access.)
-Microsoft Office Identities Cache 3
-Microsoft Office Identities Settings 3
-Microsoft Office Ticket Cache - Then restart your Mac and open any Microsoft Office app to reactivate.
Besides, here is an official article "What to try if you can't install or activate Office for Mac", you may have a look.
Any updates, please let me know.
