Normally, the password you use for all college resources expires at the same time.
However, during COVID, a discrepancy has occurred between the email and StarID systems that allows an email password to expire earlier.
Do can NOT change your password through the email system (or Microsoft.com). Instead, navigate to https://starid.minnstate.edu to update/reset your password.
