Frequently Asked Questions

Why did my Microsoft 365 apps suddenly disappear from my computer?

This usually happens due to background update failures, system registry corruption, or conflicting software that accidentally removes the application files or shortcuts while you are working.

Do I have to pay again to reinstall Microsoft 365 if it disappears?

No, as long as your subscription is active, you can sign in to Office.com with your linked Microsoft account and reinstall the applications at no additional cost.

Will I lose my saved documents if I reinstall Microsoft 365?

No. Reinstalling the Office applications only replaces the software program files. It does not delete or affect your locally saved documents or files stored on your OneDrive.

What if the 'Install Office' button is missing on my account page?

Ensure you are logged in with the correct account that holds the active subscription. If you are on a Microsoft 365 Family plan, check if the primary subscription owner has properly shared access with your account.
