Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
If the goal is to remove the old work or school account from a Windows device, use the device account settings rather than trying to sign in to the old account.
- Open Settings.
- Go to Accounts > Access work or school.
- Find the old work account.
- If Disconnect is available, select it to remove the account from the device.
If the account is in Outlook for Windows instead:
Classic Outlook for Windows
- Select File.
- Select Account Settings > Account Settings.
- Select the account.
- Select Remove.
- Select Yes to confirm.
This removes the account from Outlook only. It does not deactivate or delete the email account itself.
If this is an Outlook.com / Microsoft account and the goal is to permanently close it, that requires closing the Microsoft account. To close an account, sign-in is required. If sign-in is not possible, use the support path provided on the Microsoft account help page.
