Frequently Asked Questions

Why is my Mac confusing my Office 2019 purchase with Microsoft 365?

This commonly happens if a Microsoft 365 trial was pre-installed or previously used on your Mac. The system retains the subscription license files, which take priority and override your standard Office 2019 activation.

Will using the License Removal Tool delete my Excel spreadsheets?

No, the License Removal Tool only clears activation files and account credentials. It will not touch, move, or delete any of your personal documents, spreadsheets, or application preferences.

How do I verify which account is linked to my Office 2019 purchase?

You can verify your purchase by logging into the Microsoft account page online. Navigate to the 'Services & subscriptions' section to confirm that the Office 2019 license is actively tied to that specific email address.
