Revoke logged in 365 session.
A user logs into O365 for business account and begins using services such as SharePoint online or One drive for Business, but leaves it logged it and loses the laptop. We can remotely terminate the session of that user.
Within SharePoint Online Powershell:
Revoke-SPOUserSession -User Khalid.firstname.lastname@example.org
That’s it all O365 sessions will log out, so now data will be visible.
