If you think your account has been compromised, the first step is to change your password by logging in to a school computer while on the school network and hitting ctrl-alt-delete and selecting "Change Password," then walking through the password reset process. 

Following the password reset, go to the link below and click on "Sign Out Everywhere" to initiate a signout of your Microsoft account on all computers and phones it's currently logged in to. Note that there is a link here to Change password... however, please note that since our passwords sync from our school network this won't work -- if you change your password with this method, it will revert to the old password within about an hour. 


If you feel your account has been compromised, you should also check your mailflow rules to make sure the attacker hasn't set up a method to continue exfiltrating information from your account.
