Sign Out from Seamless Single Sign-On
With SSO, applications such as Outlook, Edge, Teams, and Onedrive automatically sign you into the service by taking the credentials that were initially used to log in to the computer. If you would like to remain signed out, you can follow the steps outlined below to sign out from these services.
Outlook pre-populates the email address that you would like to configure. You can always change the email address if you are trying to configure the profile for a shared mailbox or IMAP profile.
Onedrive silently signs into your account to enable file syncing. However, you can right-click on the Microsoft OneDrive icon in the system → Settings → Account tab → Stop sync for the account to avoid syncing.
Navigating to http://myapps.microsoft.com from an Edge browser auto-signs into the account. However, you can always click on the initials of the account on the top right corner of the page and click “Sign Out” or “Sign in with a different account.”
