Frequently Asked Questions

Why does Word for Mac keep defaulting to my old work account?

Macs cache previous login tokens in the Keychain and deep within system library folders. Unless these are fully purged using the license removal tool, Word will continue to attempt using the saved, outdated credentials.

Will removing the Office license delete my Word documents?

No. Removing the license only deletes the hidden system files that authorize the software. Your locally saved documents and files stored on OneDrive will remain perfectly intact.

Can I run both my personal and work accounts on Word for Mac?

Yes, you can activate Office with one primary account and then add other Microsoft accounts as connected services. This allows you to access cloud storage for both accounts via the 'Open' menu without licensing conflicts.
