Apart from using the Outlook Web App or HKUST Webmail, you can access to your mailboxes using email clients like Microsoft Outlook or your mobile device. The Exchange ActiveSync connection is recommended for both Staff Exchange users and @Connect users when you configure your email clients. For mobile users, it is recommended for you to select the account type Microsoft Active Sync / Microsoft Exchange or Corporate when adding your Exchange account / your @Connect account to your mobile device.

Most email clients also support the IMAP or POP access to the mail server and users are free to configure your email applications to use Exchange Active Sync / IMAP  or POP connection.
