Open any Office application (like Word) on your Mac. Click on the 'Word' menu at the top, select 'Sign Out', and then completely close the application.

Sign back in

Relaunch the applications on both devices. Tap or click 'Sign In' and enter the credentials for the Microsoft account associated with the new Family subscription.

Frequently Asked Questions

Do I need to uninstall Office when switching from Microsoft 365 Personal to Family?

Generally, no. Simply signing out of your Microsoft account within the apps and signing back in with the updated account is usually enough to refresh the subscription status on your devices.

Why is my iPhone OneDrive syncing deleted files after changing subscriptions?

This happens when the OneDrive app holds onto a cached state from your previous Personal subscription. Signing out of OneDrive entirely on your iPhone and signing back in will clear this cache and resolve the sync loop.

What should I do if my Mac still shows the old Microsoft 365 Personal subscription?

You can use the official Office for Mac License Removal Tool provided by Microsoft. This tool clears out hidden license files. Afterward, restarting your Mac and signing back in will fetch the new Family license.

Will I lose my files or OneDrive data when switching to a Family plan?

No, your files and data are tied to your Microsoft account. Switching from Personal to Family simply upgrades your subscription tier and storage limits; your existing files, emails, and photos remain fully intact.
