Frequently Asked Questions
Will I lose my Word and Excel files if I uninstall Microsoft 365?
No, uninstalling or reinstalling Microsoft Office applications only removes the software components. Your personal files, folders, and documents saved locally or synced to OneDrive remain completely safe.
Why does my Microsoft 365 suddenly say unlicensed?
This commonly happens due to an expired subscription, signing in with the incorrect Microsoft account, a billing failure, or a recent system update that temporarily disrupted the software's connection to Microsoft's activation servers.
What is the Microsoft Support and Recovery Assistant (SaRA)?
The Microsoft Support and Recovery Assistant is a free diagnostic tool provided by Microsoft. It runs tests to figure out what's wrong with Office installation, activation, or Outlook setups, and offers automated solutions for the identified problems.
