Problem with Outlook E-Mail (Mogul)

[lowpro3210]

Ok, I just put the "threaded SMS" on my phone. I then tried to set up a my email account on my phone, by entering my email address @columbus d0t rr d0t com (<~~would not let me actually put the real deal since I am new to this site...no posting URLs it said until 2 legitimate posts are made) (BTW I have Outlook 2003 on PC), but it said could not be found. So I synced it to my PC, then went to Tools, then in ActiveSync and clicked on Email so it would set it up that way. The problem I am running into is when I am in Outlook Email on my phone, I put the last 3 (most previous) emails on the phone, I go to Menu on the bottom right, and try and click on Send/Receive (but it's greyed out) to get any new emails (I sent an email to myself just to see if it would work; and was connected to internet) and nothing. PLEASE help
