Question details

The user needs to resolve an issue where Microsoft Word prompts for activation and reports an unsupported version after a Microsoft 365 renewal.

Product: Microsoft Word for Mac
Device & OS: macOS Sonoma 14.6.1 (Mac Pro)
Scenario: Attempting to use Microsoft Word on a Mac after recently renewing a Microsoft 365 subscription.
Observed behavior: Word reports that it is not supported with the installed version and continuously requires activation, even though the user is successfully signed in with their active Microsoft 365 account.

Before you start

Ensure you know the exact Microsoft account credentials tied to your renewed Microsoft 365 subscription, and save any open documents before making changes to your software.

Solution 1Recommended

Verify Software Version and License Mismatch

Check if the installed application is an older perpetual version (like Office 2019) conflicting with a newer Microsoft 365 subscription.

A common cause for activation loops on Mac is a mismatch between the software installed on your computer and the license attached to your account. If you originally installed Office 2019 but recently renewed a Microsoft 365 subscription, the 2019 software will not recognize the new subscription.

Check installed version

Open Microsoft Word on your Mac. Click on 'Word' in the top Apple menu bar and select 'About Microsoft Word'.

Review license details

Look for the 'License' field in the dialog box. Note whether it says 'Office 2019', 'Microsoft 365', or 'Not Activated'.

Compare with online account

Log into your Microsoft account portal online and navigate to 'Services & subscriptions' to confirm what license you actually own. If they do not match, proceed to uninstall and reinstall the correct version.

Solution 2

Remove Old License Files and Reinstall Office

Use Microsoft's official tools to wipe outdated license data and install the correct software version for your subscription.

Frequently Asked Questions

Why does my Mac say my Word version is unsupported?

This usually happens when you have older software installed (such as Word 2019) but your Microsoft account is tied to a newer or different subscription plan (like Microsoft 365). The old software cannot validate the new license.

Will using the license removal tool delete my Word documents?

No, the Microsoft License Removal Tool only clears the hidden activation data and cache files on your Mac. It will not touch or delete your personal documents, templates, or files.

How do I find out which version of Office is installed on my Mac?

Open any Office application, such as Word, click on the application name in the top-left menu bar, and select 'About Microsoft Word' to view the exact version number and license type.
