Can I receive email addressed to @ust.hk or @stu.ust.hk after migrated to @Connect?

Yes. You can keep receive messages addressed to your xxxxx@ust.hk or xxxxx@stu.ust.hk account after switched to @Connect because they will become email aliases of your xxxxx@connect.ust.hk email address.

However, the email aliases will be removed when your ITSC network account is expired, i.e. after your are graduated from HKUST.
