Fix Microsoft 365 Installing with Former Business Account on Mac
Question details
The user is unable to activate a new personal Microsoft 365 Family subscription because the installation continues to use a former employer's business license.
- Product
- Microsoft 365
- Device & OS
- Mac
- Scenario
- Switching from a business Microsoft 365 account to a personal Microsoft 365 Family subscription.
- Observed behavior
- Old Office license files persist on the Mac even after standard uninstallation, forcing the reinstalled applications to detect and use the invalid business account instead of the new Family subscription.
Make sure you know the email and password for your personal Microsoft account associated with the Family subscription, and save any open work before proceeding with license removal.
Clear Old Licenses using the License Removal Tool
Use Microsoft's official utility to completely erase hidden business license tokens from your Mac, allowing a fresh activation.
A standard uninstallation by dragging Microsoft Office applications to the Trash does not remove license files stored deep within your Mac's Library and Keychain. The License Removal Tool is specifically designed to clear these persistent files so you can sign in with a different account.
Visit the official Microsoft Support website, search for 'Office License Removal Tool for Mac', and download the utility package.
Open the downloaded .pkg file. Follow the on-screen installation wizard prompts and click 'Install' to execute the license wipe. You may need to enter your Mac administrator password.
Launch any Microsoft 365 application, such as Word or Excel. When the 'What's New' window opens, click 'Get Started' and sign in using your personal Microsoft account tied to your Family subscription.

Frequently Asked Questions
Why didn't deleting the Office apps remove the old business license?
Dragging Microsoft Office applications to the Trash only removes the software execution files. macOS securely stores license tokens in hidden system library folders and the Keychain, which require a specialized removal tool to clear.
Will running the License Removal Tool delete my documents or emails?
No. The License Removal Tool only targets hidden activation and license files. Your personal documents, spreadsheets, Outlook data, and system settings remain completely untouched and safe.
How can I check which account is currently activating my Microsoft 365?
Open any Office application, such as Microsoft Word. Click on 'Word' in the top Apple menu bar, then select 'About Microsoft Word'. A dialog box will appear displaying the license type and the email address under 'Belongs to'.
