How do I connect my Gmail to my Outlook 2003?

One of three computer's Outlook Calendars won't sync or connect to Microsoft Exchange Server.How do I fix it ?

• The office area I work at has a back office, side office, and front office. Outlook calendars are synced through Microsoft Exchange Server. Any of the computers can make a change on the Outlook calendar and the other computers can see the change on Outlook. The office I work at went to Comcast business internet and phone services. We got it because of the Microsoft Exchange Service that comes with the package. We wanted it so we can make changes on one of the Outlook calendars at one desk and we can see it on the other Outlook calendars at a different desk. The side office computer wont show any of the new calendar changes/updates that are made from the other computers. The back office and front office can make a change on Outlook Calendar and they can see the change/update in a few minutes. Front office has Outlook 2007 and the others office computers have Outlook 2003. It was working fine for about 2 weeks. I got the run around from both Microsoft and Comcast. Both are saying it is the other companies fault and need to talk to them. I have turned off all the computers and reset/ unplugged the Comcast modem and our router. Plugged power back into the Comcast modem and waited for all the lights to light up, then did the same to the router. Then I turned on all the computers and the side office still wont sync/update with Microsoft Exchange server.
