4. (For Student Organizations) Switchover Exercise from CUHK Webmail to @Link in Year 2017

ITSC had coordinated and communicated with the student organization account users in 2017 to prepare for the switchover from the old email email, CUHK Webmail, to @Link. The switchover exercise included

An @Link mailbox was offered to the student organization with other cloud services e.g. OneDrive, and collaborative tools available for students.
A new email address = alias@link.cuhk.edu.hk (if defined) / computing-id@link.cuhk.edu.hk was created, which was also the reply-to email address / sender email address.
Student organizations could use computing-id@link.cuhk.edu.hk & OnePass password to log in @Link mailbox.
If student organization had defined email address as alias@cuhk.edu.hk which was published in different publications, to avoid email loss, any new emails reaching that email address would be forwarded to @Link. However, in a long term, those student organization should publish their new email address alias@link.cuhk.edu.hk instead.
If student organization had never defined its email address i.e. email address = computing-id@cuhk.edu.hk, it became invalid on 3 Jan 2018.
