Word for Mac Office Add-ins authentication fails, but works in Word Online
I have received advice from the Word Product Team at Microsoft that the issue has now been resolved with a change on the service side.
A small number of users may still see the issue if their device is using cached credentials. They can work-around the issue by signing-out and back in or waiting for the token to expire.

Thank you so much for following this up with the Word Product Team. I can confirm that the issue has now resolved on my end as well.
As of September 26, Claude for Microsoft 365 is working normally in Word for Mac again. I didn't make any further changes or perform any additional troubleshooting, so this appears consistent with the service-side fix you described.
I really appreciate your help in escalating this and getting to the bottom of the issue!
