Revert to the Correct Version of Office 2019

Uninstall the incorrect version of Office installed by Microsoft AutoUpdate and reinstall the final supported version for your one-time purchase.

If you purchased a one-time license for Office 2019, Microsoft AutoUpdate may have mistakenly upgraded your software to a newer version that requires a Microsoft 365 subscription. This locks your editing capabilities.

To fix this, you must remove the incorrect version and install the final supported version of Office 2019 for Mac, which is version 16.78.3.

1
Uninstall the current incorrect Office version

Open the Applications folder on your Mac, locate all Microsoft Office applications (Word, Excel, PowerPoint), and drag them to the Trash to completely uninstall them.

Download the final Office 2019 version

Search for and download the Microsoft Office 2019 for Mac version 16.78.3 installer from the official Microsoft release history page.

3
Install the correct version

Run the downloaded installer package and follow the on-screen prompts to install Office 2019 on your Mac.

4
Disable Microsoft AutoUpdate

Open Microsoft Word, go to the 'Help' menu at the top, select 'Check for Updates', and disable the automatic updates option to prevent AutoUpdate from upgrading you to a subscription version again.

Revert to the Correct Version of Office 2019
Verification: After signing in to the newly installed version 16.78.3 with your Microsoft account, your one-time license will be recognized, and editing features will be restored.
