How to Log In to Office 365

Logging into Office 365 is easy to do is you know your username and password. Usernames are a little different for students and staff.

Staff Usernames

Staff usernames are the same ones they use to log on to the computer (usually lastname.firstname), but with the @cusd80.com domain added to the end. So a teacher whose computer username is jacobson.brad would use jacobson.brad@cusd80.com to log on to Office 365.

Student Usernames

Student usernames are the same ones they use to log on to the computer, Infinite Campus, etc., (S + ID number), but with the @s.cusd80.com domain added to the end. Notice that this is not the same domain as staff ... it has the s. added to the beginning to identify it as a student account. So a student whose ID number is 123456 would use S123456@s.cusd80.com to log on to Office 365 (the S in the username can be uppercase or lowercase).

Passwords

Your password for Office 365 is the same one you use to log on to a district computer, Infinite Campus, etc. If you have forgotten your password or need to reset it, please visit our password assistance page.
