Resolution

Download and run the license removal tool

1. Download the license removal tool.

Note: If you get an "unidentified developer" error, try opening the file by holding Control + clicking the file > Open.

3. Select Continue and follow the prompts in the setup wizard.

Caution: We recommend you double-check that you have the correct account info ready by logging into Office.com/signin and checking for the license you want to activate with.


                                                                   

4. When you're ready to complete the license removal, select Install. You may need to enter your Mac's local admin account password.

After the tool successfully removes licenses, select Close.

                                     

5. Now open any Office app and sign in to activate with the email account associated with your Office for Mac license. If you're troubleshooting an issue, you may need to reinstall Office before signing in.

After you've successfully activated, restart your computer and then you're good to go!

Note: If your account has both a Microsoft 365 for Mac license and a one-time purchase associated with it, you'll be prompted to choose which license you want to activate with. We recommend always choosing Microsoft 365 for Mac is available.

6. Uninstall the License Removal Tool by dragging the Microsoft_Office_License_Removal file from Finder > Downloads to Trash.
