Frequently Asked Questions

Why does Microsoft AutoUpdate say "Upgrade Required" when I have Microsoft 365?

This usually happens if you previously had an older version of Office (like Office 2019) installed on your Mac. AutoUpdate detects the old configuration files or lingering components and flags them as unsupported, even if your new Microsoft 365 license is active.

Will reinstalling Office on my Mac delete my existing documents?

No, uninstalling and reinstalling Microsoft Office applications only removes the software files. Your personal documents, spreadsheets, and presentations saved on your local Mac drive or in OneDrive will remain completely safe and untouched.

How do I use the Microsoft License Removal Tool?

You can download the License Removal Tool from the official Microsoft Support website. Once downloaded, close all Office apps, run the tool package, and follow the on-screen prompts to clear out all existing Office license files before you attempt to reinstall Microsoft 365.
