Steps to Disable a Microsoft 365 Account

  • Block Sign-in: In the Admin Center, select the user, click the Block sign-in icon (resembles a stop sign), and select “Block this user from signing in”.
  • Reset Password: Select the user and choose “Reset password” to prevent further access.
  • Remove Licenses: After blocking sign-in, remove licenses to free them up for other users.
  • Sign Out of All Sessions: Force a sign-out of all current active sessions. 

Important Considerations

  • Data Retention: When a license is removed, user data is typically deleted after 30 days.
  • Shared Mailbox: Convert the mailbox to a shared mailbox if you need to retain email access without paying for a license.
  • Alternative Methods: You can also use PowerShell to block sign-in or disable accounts via the Entra ID portal.
  • Local Removal: If removing the account from a local machine, remove credentials from the Windows Credential Manager.
