In addition to the Outlook Web App or HKUST Webmail, you can access your mailboxes through email applications such as Microsoft Outlook or your mobile device.

Both Staff Exchange and @Connect users are recommended to use the Exchange ActiveSync connection when configuring email applications. Mobile users are recommended to select Microsoft ActiveSync/ Microsoft Exchange or Corporate when adding their Exchange/@Connect account. Most email applications also support IMAP or POP access to the mail server and users are free to use Exchange Active Sync/IMAP or POP connection.
