This email service is available to CUHK retirees as defined by the Human Resources Office. It offers basic email functionalities, including sending, receiving, and storing messages, along with a personalized email address in the format xxx@e.cuhk.edu.hk.
You may opt in to the Reminding Service prior to retirement. For up to three years after retirement, an automatic reply will be sent to anyone who emails your default CUHK staff address (xxx@cuhk.edu.hk).
If you take up a new appointment after retirement, this automatic reply feature will be disabled automatically. Should you wish to reactivate the feature after the completion of your service, please contact us.
