On July 1, 2014 the ScarletMail system will become the only student email service at Rutgers University. More information is available about the decommissioning of student campus email services, but the TL;DR version is this:
On July 1, 2014 this web mail service for students will be deactivated. Existing student mail will not be immediately deleted on that date, but it will be placed into a read-only archive for a period of time before it is eventually deleted. You should begin using the ScarletMail service in place of this web mail service before July 1, 2014.
