What are my O365 Account Username (or UserID), Password and Email address?

  • Your CityU Office 365 (O365) Account Username (or UserID) is in the form:
            EID@um.cityu.edu.hk
    where EID is your CityU Electronic ID.
    e.g. if your EID is "cctom", your O365 account User Name/ID is "cctom@um.cityu.edu.hk".
    You will use this O365 Account Username/UserID to sign in your O365 account through the web, or set up your mobile device or popular Email Client Software to access your O365 account.

  • The Password of your O365 account is the same as your AD/Exchange password.

  • The "Email Address" of your O365 account is in the form of "user@cityu.edu.hk". Your O365 account can have one Primary Email Address and one or more Non-primary Email Addresses. The Primary Email Address will be set as the Sender Address for all email sent from your O365 account.

    If you have not yet registered an Email Alias for your EID, the Primary Email Address of your O365 account is "EID@cityu.edu.hk".

    If you have registered an Email Alias for your EID, the Primary Email Address of your O365 account will be "your-email-alias@cityu.edu.hk", and the address "EID@cityu.edu.hk" will be the Non-primary Email Address of your O365 account.

    e.g. if your EID is "cctom", and you have not registered an Email Alias, your O365 account Primary Email address is "cctom@cityu.edu.hk".
    However, if you have registered an Email Alias "Tom.Chan" for your EID "cctom", your O365 account Primary Email address will be "Tom.Chan@cityu.edu.hk", and "cctom@cityu.edu.hk" will be your Non-primary Email address.
