Unable to activate my email

So I'm being set up with an email account but everytime I go to log in I get a message saying "the link has expired" and that I need to refer to my activation email. The only problem is that I have no ability/way to find the activation email and my admin doesn't seem to know how to fix it either. It seems to keep getting sent to an email that I can't log in to because I don't have the activation email, kind of a circular problem here. Anyone else have this issue? Is there a way to change where the activation email gets sent
