There are different email systems at SLC.
Students use Gryphon Mail by going to gm.slc.edu. (You can also use a mail client application; see Google’s Help Center.)
Faculty and staff use Exchange by going to owa.slc.edu. (You can also use Outlook or Entourage.)
Faculty and staff not yet on the Exchange system use SLC Webmail (Squirrel Mail) by going to mail.slc.edu.
