NOTE: Your email address is still FirstName.LastName@wwu.edu, but Office 365 will prompt you to login using your User Principal Name (UPN): firstname.lastname@example.org. Think of the UPN as your Office 365 username. Depending on the application or device you are connecting, you may be prompted to enter your email address, username (UPN), or both. Your password is your Western universal password. Whenever you change your universal password your Office 365 account will be automatically updated with that new password.
