Optional Email Account for Staff on the Student Microsoft 365 (M365)
In CityU, email service for staff and email service for students (and alumni) are based on Microsoft 365 (M365),
however, the two services reside on separate environments. By default, all current staff have accounts on the Staff
and all current students and alumni have accounts on the Student M365 (@my.cityu.edu.hk).
If you want to access your primary staff M365 account, please go back to Email Services home page and click
"@cityu.edu.hk (Microsoft 365 for staff)" under "Web Login to" in "Staff" column.
If you wish to separate your office/work emails from that for teaching/communication with students, you may raise a CSC Work
Request via your department to request for creating a separate account on the Student
M365 as your optional staff account.
