Clear Previous License with Microsoft Office License Removal Tool
This is the most reliable method to completely remove the old Office 2019 activation files so your Mac can recognize the new Office 2021 license.
macOS often retains old license files deep within the system library. Simply installing a newer version does not overwrite these license files, which is why the removal tool is necessary.
Download the official Microsoft Office License Removal Tool from the Microsoft website to your Mac.
Open the downloaded .pkg file and follow the on-screen instructions to clear the previous activation files.
Once the tool finishes, restart your Mac to ensure all system changes are applied.
Open Word or another Office app and sign in with the Microsoft account that owns the Office 2021 license to activate it.
Manually Sign Out of Office 2019
A quick fix attempting to force the application to prompt for a new login by signing out of the old account directly within Word.
Switch to WPS Office for a Hassle-Free Experience on Mac
Tired of dealing with complicated license conflicts and upgrade issues on your Mac? WPS Office is a free, lightweight, and user-friendly alternative to Microsoft Office that runs flawlessly on macOS without activation headaches.
Frequently Asked Questions
Why does my Mac still show Office 2019 after installing 2021?
macOS retains previous license activation files in your system library. Even if you install a newer version like Office 2021, the applications will read the older 2019 license file first until it is manually cleared.
Do I need to uninstall Office 2019 before installing Office 2021 on Mac?
While not strictly required, it is highly recommended to uninstall the older version and run the license removal tool before installing the new version to prevent these types of version conflicts.
Why did Teams update successfully but Word did not?
Microsoft Teams handles licensing and updates differently than the core Office suite (Word, Excel, PowerPoint). Teams often updates independently of the main Office licensing files on macOS.
