How to Remove an Employer Administrator Account from a Personal Computer

Navigate to Start > Settings > Accounts > Access work or school. Locate the employer account in the list, click on it, and select 'Disconnect'.

Click on the Windows Start menu, type 'Credential Manager' into the search bar, and hit Enter to open the utility.

Select 'Windows Credentials'. Scroll through the list and look for any entries containing 'msteams', 'MicrosoftAccount', or your employer's domain. Click on each entry and select 'Remove'.

Reopen Microsoft Teams. It should now prompt you for a fresh login without defaulting to the employer administrator account.

Press Cmd + Space to open Spotlight Search, type 'Keychain Access', and press Return.

In the search bar at the top right of the Keychain Access window, type 'Microsoft Teams' or the name of your employer's organization.

Select all the relevant application passwords and cache entries that appear in the results, right-click (or Control-click) them, and choose 'Delete'.

Close Keychain Access and start Microsoft Teams to sign in with your personal credentials.

Reach out to your former employer's IT department and request that they remotely unenroll or 'retire' your personal device from their active directory.

If the employer is unresponsive and the administrator account severely restricts your personal computer, you may need to back up your personal files and perform a full system reset via Settings > System > Recovery.
