Frequently Asked Questions

Why did my Office 2021 suddenly change to Office 2016?

This usually happens due to cached credentials, an interrupted background update, or accidentally signing in with an account associated with an older Office 2016 license instead of your 2021 account.

Will I lose my documents if I uninstall and reinstall Office?

No. Uninstalling Microsoft Office only removes the application files. Your personal documents, spreadsheets, and files saved locally or on OneDrive remain perfectly safe and untouched.

How do I find out which Microsoft account has my Office 2021 license?

Visit the Microsoft account Services & subscriptions webpage and log in with your email addresses. The page will list all active Office licenses linked to whichever account you are currently viewing.

Does repairing Office through the Control Panel require an internet connection?

An 'Online Repair' requires a stable internet connection because it redownloads corrupted files. A 'Quick Repair' can be done offline but is less comprehensive.
