How to Fix Excel Linked to an Old Microsoft 365 Work Account on Mac
Question details
The user needs to switch Excel on their Mac from an old Microsoft 365 work account to a newly purchased personal subscription to stop incorrect subscription expiration warnings.
- Product
- Microsoft Excel
- Device & OS
- macOS
- Scenario
- Transitioning from a workplace Microsoft 365 subscription to a personal Microsoft 365 subscription on a Mac.
- Observed behavior
- Excel continues to recognize the old workplace account and displays an incorrect subscription-expiration warning despite the user having an active personal subscription.
Ensure you have the login credentials for your new personal Microsoft 365 account ready, and save all open Excel workbooks before running any license removal tools.
Clear Activation Data using the Microsoft Office License Removal Tool
Running Microsoft's official license removal tool is the most effective way to clear cached workplace credentials and force Excel to prompt for your new personal account login.
On macOS, simply signing out of Excel does not always remove the underlying license files hidden in the system. The official removal tool completely erases these hidden files, preventing account conflicts without deleting your personal documents.
Open the Mac App Store, navigate to the 'Updates' tab, and install any pending updates for macOS and your Microsoft Office applications to ensure compatibility.
Download the official Microsoft Office License Removal Tool from Microsoft's support website (search for 'Office License Removal Tool Mac').
Open the downloaded .pkg file and follow the on-screen installation wizard prompts. The tool will automatically detect and remove the existing Office activation data from your Mac.
Once the tool finishes successfully, restart your Mac to ensure all cached license files are completely cleared from the system memory.
Open Microsoft Excel. You will be prompted to activate the software. Click 'Sign In' and enter the email and password for your newly purchased personal Microsoft 365 subscription.
Switch to WPS Office for a Hassle-Free Spreadsheet Experience
Tired of dealing with complex Microsoft 365 subscription conflicts and expiration warnings? WPS Office provides a lightweight, highly compatible alternative for Mac that doesn't require frustrating license management tools.
- 1. Download WPS Office: Visit the official WPS website to download the free installer designed specifically for macOS.
- 2. Install the Suite: Open the downloaded package file and drag the WPS Office icon into your Applications folder.
- 3. Open Your Existing Spreadsheets: Launch WPS Spreadsheets to instantly open, edit, and save your existing Excel workbooks without facing activation barriers.
Frequently Asked Questions
Why does Excel on Mac keep remembering my old work account?
Mac's Keychain and Office's internal caching persistently store activation files to make logging in easier. Simply signing out often doesn't delete these hidden license files, which is why a dedicated removal tool is required to break the link.
Will using the License Removal Tool delete my Excel files or formatting?
No, the tool only removes the activation and license data stored deep within your Mac system files. Your personal documents, spreadsheets, formats, and data will remain completely intact.
What should I do if the License Removal Tool doesn't fix the expiration warning?
If the tool fails, open the 'Keychain Access' app on your Mac, search for 'Office' and 'ADAL', and manually delete those cached password entries. Afterward, completely uninstall and reinstall the Microsoft Office suite.
Can I use both a work and personal account on Excel for Mac simultaneously?
Yes. The software license is activated by your primary account, but you can add multiple connected services within Excel (like OneDrive for Business and personal OneDrive) by going to your profile picture in the top left and clicking 'Add an Account' to access cloud files from both.
