MSU provides Microsoft 365 licenses to all students, faculty, and staff. In order to access and begin using the licensed applications, you will need to sign in using your MSU-UPN. 

What is your MSU-UPN ?

When you attempt to use a Microsoft application that requires you to sign in, it will typically ask for an email.

UPN is short forUser Principal Name
Technically speaking, a UPN  is an attribute that is an Internet-style login name for a user based on the Internet standard.

A UPN consists of a UPN prefix (the user account name, or NetID) and a UPN suffix (a DNS domain name). The prefix is joined with the suffix using the "@" symbol.
example: [email protected]

We call it the MSU-UPN because not all campuses use the same format, so we call it that to differentiate between other campus' formats.
