How to Remove an Office 365 Account From Windows 11

To remove an Office 365 (Microsoft 365) work or school account from Windows 11, open Settings > Accounts > Access work or school, click the account, and choose Disconnect. If it’s listed under Settings > Accounts > Email & accounts instead, click it and choose Remove. To stop Word, Excel, and Outlook from using it, open any Office app and go to File > Account > Sign out. If your PC is managed by your organization, ask IT before removing it, because you may lose access to company apps and email.

Step 1: Sign out of the Office apps

1. Open Word, Excel, or another Office app.
2. Click File > Account.
3. Under User Information, click Sign out and confirm.

Signing out in one Office app signs you out of all of them on that PC.

Step 2: Disconnect the work or school account from Windows

1. Open Settings > Accounts > Access work or school.
2. Click the account you want to remove.
3. Click Disconnect, then Yes to confirm.
4. Restart your PC.

If Disconnect is missing, your PC is joined to your organization (Microsoft Entra joined or managed by Intune). Only an administrator can remove it.

Step 3: Remove it from Email & accounts

1. Open Settings > Accounts > Email & accounts.
2. Under Accounts used by other apps or Accounts used by email, calendar, and contacts, click the Office 365 account.
3. Click Remove (or Manage > Delete account from this device).

Step 4: Clear saved credentials (optional)

1. Open Credential Manager from the Start menu.
2. Click Windows Credentials.
3. Remove entries that start with MicrosoftOffice or mention your work email.

This stops Office from signing you back in automatically.

Remove the account from Outlook

1. In classic Outlook, go to File > Account Settings > Account Settings, select the account, and click Remove.
2. In the new Outlook, click Settings (gear) > Accounts, choose the account, and click Remove.
