1. Enter your email address (e.g. someone@ust.hk)
   
   
2. Select Work of school account if prompted
3. You will be redirected to HKUST User Authentication Service, enter your password to sign in (make sure that it is a secured connection with URL starting with https://adfs.ust.hk/...)
   
4. If any user has enrolled for two-factor authentication, you will need to login using your Account / Password and then use your device to verify your identity.

If your browser (e.g. Internet Explorer) already connected to other Microsoft web mail service such as hotmail, you will need to use New session under the File menu before you can sign on to Office 365. For Firefox or Chrome, please use New Private Window or New incognito window.
