Why can't I log on to O365?

There are a couple of reasons why you may not be able to log on to O365.

    Make sure you are logging in with your O365 email address and your O365 password, not your UMKC Username and its corresponding password. If you were previously a student at another University of Missouri school (Columbia, UMSL, MST), or you applied to and were admitted to another University of Missouri school prior to being admitted to UMKC, your O365 account was assigned to that school rather than to UMKC. You will need to contact the UMKC IS Technology Support Center so we can move your account from that campus to UMKC.

These instructions are provided as guidance. If you experience difficulties feel free to contact the UMKC IS Technology Support Center.
