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.
This is a known issue with Office Web Add-ins authentication on Word for Mac: the desktop client sometimes fails to pass authentication tokens correctly, even when Word Online works.
May try on below:
- Clear the add-in cache folder and reinstall Word.
Thanks for the suggestion. I did clear the Office/Word add-in cache during troubleshooting, although I didn't reinstall Word. Unfortunately, clearing the cache didn't resolve the issue at the time.
The issue has since resolved without any further changes on my end, following Microsoft's service-side fix. Claude for Word is now working normally again.
Thank you again for taking the time to help.
