How to Remove a Legacy Work or School Account Without Affecting Office
Question details
The user wants to remove an old work or school account that forces an account choice during sign-in, without disrupting access to their personal Microsoft 365 apps or OneDrive files.

- Product
- Microsoft 365 / Office
- Device & OS
- not provided
- Scenario
- A legacy developer work account and a personal Microsoft 365 account are linked, causing sign-in conflicts.
- Observed behavior
- The system prompts the user to choose between accounts during sign-in, and the user needs to cleanly remove the legacy work account while keeping personal subscriptions and files intact.
Before removing the old account, ensure you have manually downloaded or transferred any important files from the legacy OneDrive to your personal storage, and confirm your new personal Microsoft 365 subscription is fully active.
Disconnect the Legacy Account and Update Office Sign-In
Safely transfer your files, disconnect the old work or school account from your system, and switch to your active personal subscription in the Office apps.
Since the Office application is the same product across different Microsoft 365 plans, you do not need to uninstall and reinstall the software. You simply need to ensure your files are backed up and the correct account is signed in.
Log into the legacy work or school account's OneDrive. Download any necessary files to your local hard drive, then upload them to your personal OneDrive account to prevent data loss.
If you have a family plan, log into your new personal Microsoft account and reshare the subscription with your family members before the old legacy subscription expires.
Open Windows Settings, navigate to 'Accounts', and select 'Access work or school'. Click on the legacy work or school account you wish to remove, and click 'Disconnect'.
Open any Office application such as Word or Excel. Go to 'File' > 'Account', click 'Sign out' under the old work account, and then sign back in using the credentials of your new personal Microsoft 365 account.

Frequently Asked Questions
Do I need to uninstall Office when switching from a work account to a personal one?
No, you do not need to uninstall Microsoft Office. Since the core product installation is identical, you just need to sign out of the old account under File > Account and sign in with the new personal account.
What happens to my OneDrive files if I remove the legacy work account?
Any files stored exclusively on the legacy account's OneDrive will become inaccessible once the account is removed. You must manually download these files and move them to your personal OneDrive or local storage beforehand.
How do I ensure my family members keep their Office access?
Before the old subscription expires, set up your new Microsoft 365 subscription and send new sharing invitations to your family members. They can then link their accounts to the new active license.
Will removing the work account affect my Windows login?
Removing a work or school account from your device's settings will only remove access to the organization's resources. As long as you log into Windows with a personal Microsoft account or local account, your PC access remains unaffected.
