There are three different methods to backup NTU mails: Gmail backup, Outlook setup rules, and Outlook archive backup. For more details please refer to the following link: http://homepage.ntu.edu.tw/~nickyyang/mail2.0/usage-Exchange.html.
Here we provide the instructions for Outlook setup rules.
Outlook archive backup:
- Sign in Outlook mailbox, and make an archive file.
- Open the [Outlook file(.pst)], and the backup is done.
Pro: Can backup personal folder.
Con: Need to be archived at regular intervals.
(warning: after archive, mails in the original inbox would be gone)
