We are implementing some single sign on improvements for Office 365 services (email for now), when logged into a campus computer. These improvements will reduce the number of times a student is required to sign in when accessing their email. With this ease of access comes more responsibility.
Not doing so can potentially give others access to your email account. In order to securely log off of a school computer you will need to choose the 'Log Off' option in Windows via either the Start Menu or by pressing Alt - Ctrl - Del, and choosing 'Log Off.'
