After your userid and password have been verified, a series of options appears. You may also wish to select the 'Vacation Message' option. You can use this as a way to send notification of your new address to all your UofM correspondents. If your mail is being forwarded your vacation message should also inform them of this, so that they know not to re-send the same message. You can access this Web-based mail server page to change your account options at any time before you leave or after you arrive at your destination.
Web access is all that is required.
