Signing In: Microsoft 365


How to log into Microsoft 365 (formerly Office 365)



CSUMB students and faculty have access to Microsoft 365 (formerly Office 365) on personal computers. Your CSUMB Microsoft Account uses Single Sign-On (SSO) to log in. 

  • Current CSUMB students and faculty get Microsoft 365, formerly Office 365, accounts automatically. You obtain access by going to and signing in with your CSUMB credentials.

  • Current CSUMB staff do not automatically get Microsoft 365 access. If they need access to Microsoft 365 on their personal machines they will need to submit a service ticket.

Note: This does not affect CSUMB-issued computers.

Signing in to Microsoft 365

If you leave CSUMB, graduate or are no longer an active CSUMB student or employee, you will lose access to Microsoft 365 services and any stored data will be deleted and can’t be recovered.

You will then be taken to the Microsoft365 product you were signing into.
