UM System Information Technology will upgrade the email authentication used systemwide on Wednesday, January 8, 2020. These changes are a step in adding additional security to your University email account. If you experience any issues, the first step is to reboot your computer. If you continue to encounter problems, please contact your local IT Help Desk. Note that webmail access will work even if you are having problems logging in through your computer applications. You can get more information from our Secure Authentication FAQs.
