The installation of Microsoft Office 365 for education requires prior activation of the service according to the instructions found here. Please be advised that Microsoft may require up to 1 hour to finalize the activation of your service before you are able to log in to portal.office.com.

You access the portal.office.com website and you enter your Microsoft Cloud identity as your email address. This identity follows the format: <username>@office365.auth.gr.

Once you press Tab on your keyboard or select Sign in, you will be automatically redirected to the University’s authentication page (login.auth). There, you must enter your institutional user account credentials to complete the login process.
