If you are leaving the University soon, you may wish to set up change-of-address autoreplies so that people sending mail to your @cam address will be informed how to contact you after you have left. You can read more information on dealing with email when you leave Cambridge and instructions on how to alter delivery arrangements for your @cam address.
If you receive a message asking you for your email login details then DO NOT REPLY and do not click on any web links in the message. These messages are sent by criminals who want to use your account to send spam. You should never reveal your password to anyone, not even to University IT staff.
