On Wednesday, May 20th, your student login ID and password for your University Microsoft 365 account changed. This is the login ID and password you will use to access your University email account as well as other Microsoft resources such as Teams or OneDrive. Going forward, your Microsoft 365 login ID will always be your username with @umsystem.edu. Your actual email address and any personalized aliases that you have setup will not change. This login id format username@ umsystem.edu will soon become the standard for access to all University electronic resources.
Any email apps you have setup will need to be reconfigured with your new login id and password, this includes mobile and desktop clients (MS Mail, MS Outlook). Visit O365/MFA Implementation FAQ for more information on how to set up your device.
