    Hi @IniobongNkanga-8038

    You could try to do all of the following steps to regain control of the account. Go through the steps as soon as you suspect a problem and as quickly as possible to make sure that the attacker doesn't resume control of the account.

    1)Reset the user's password

    2)Remove suspicious email forwarding addresses

    3)Disable suspicious Inbox rules

    4)Unblock the user from sending mail

    5)Block the user account from signing-in
