Pause sending when a mailbox may be compromised
Stop a user from sending while they can still receive mail, then fix the cause.
Open Active users
Look for a user whose Sent (hour) number is unusually high, or one marked sending paused by the automatic protection.
Select Pause sending
Confirm the question. The user can still receive mail and sign in, but cannot send.
Find and fix the cause
Reset the user’s password, check Sign-in activity for failed or unknown sign-ins and ask the user to scan their device for malware.
Select Resume sending
When the mailbox is safe, select Resume sending on the row.
