Hi Leland
I'm Anna and I'd be happy to help you with your question. In this Forum, we are Microsoft consumers just like yourself.
Sorry for the trouble this might have caused. Follow these directions to restore your keychain permissions:
Quit out all Microsoft 365 for Mac apps such as Word, Excel, PowerPoint, Outlook, and OneNote.
Search for "keychain" in Spotlight and launch the Keychain Access app.
Select the login keychain entry in the top left navigator pane, then from the File menu, choose Lock Keychain "login".
Launch any Office app, such as Word.
You'll receive a prompt requesting permission to access the keychain. Enter your Mac admin account password and click OK.
If prompted, sign in to your account associated with Office.
Once you have successfully signed in, quit the application and open it again. You should be able to open the app without any more prompts.

I hope this helps ;-), let me know if this is contrary to what you need, I would still be helpful to answer more of your questions.
Best Regards,
Anna
