Hi SteKelly,
Thanks for your reply.
To delete the Keychain and UBF folder is clean the old Office credential to reactivate your Mac.
Please try to open Finder > Applications > Utilities > Keychain Access and remove the following password entries:
Microsoft Office Identities Cache 2
Microsoft Office Identities Settings 2
Restart your Mac and open any Microsoft Office app to reactivate.
If it not useful, you may also try the following steps to delete the old Office credential files in your Mac:
- Click Go on the start screen of your Mac and choose Go to Folders in the drop-down options;
- Type ~/Library/ in the open window and click Go;
- Find the 3 UBF folders and move it to the desktop:
- UBF8T346G9.ms
- UBF8T346G9.Office
- UBF8T346G9.OfficeOsfWebHost
Note: This will remove the licenses and you need to reactivate Office. You may need to

your emails in case of any data lose.
In addition, the Grant Access errormay caused by the updated Apple sandboxing rules. Apple now uses sandboxing to limit various actions by tying them to a specific location.
Application sandboxing is very effective in preventing viruses or other malware from affecting OS files.
