How to Remove a Work Account from Office Activation on Mac
Question details
Users are unable to activate Office Home on their Mac because the software defaults to a cached work account instead of their personal license.
- Product
- Microsoft Office
- Device & OS
- Mac
- Scenario
- Activating a personal Office Home license on a Mac that previously used or connected to a work account.
- Observed behavior
- Office Home activation continuously fails due to lingering work account details and cached license files overriding the personal account login.
Ensure you have the login credentials for your correct personal Microsoft account and close all open Office applications on your Mac before proceeding.
Use the Office License-Removal Tool
Clear all residual account data and cached licenses to allow a fresh activation with your personal account.
Simply uninstalling Office does not remove the hidden license files or Keychain credentials associated with your work account. You must use the official removal tool to reset the activation state.
Search for and download the official Microsoft Office license-removal tool for Mac from the Microsoft support website.
Open the downloaded package, follow the installation prompts, and run the tool to completely clear out cached license files and residual work account data.
Reinstall Microsoft Office for Mac. Open any application like Word, click 'Sign In', and enter the credentials for the personal Microsoft account that owns the Office Home license.
To prevent your Mac from caching work credentials in the future, always use a private or incognito browser window when accessing work resources online.

Frequently Asked Questions
Why does my Mac keep logging into my work account for Office?
Your Mac stores login credentials in the Keychain and caches hidden license files. If a work account was previously used on the device, Office will default to it until those specific license files are thoroughly cleared out using the removal tool.
Will using the license removal tool delete my saved documents?
No. The license-removal tool only deletes activation files and account associations. Your local documents, spreadsheets, and presentations will remain completely untouched and safe on your Mac.
How can I check which account is currently active in Office for Mac?
Open any Office app (like Word), click on the application name in the top menu bar (e.g., 'Word'), and select 'About Word'. Look for the 'Belongs to' section to see the email address currently associated with your activation.
