I have a facilities that insists on having a very old 3Com Firewall between our 
organizations.  On his side of the firewall is has 400 + outlook clients, on my side I 
have the Exchange 2003 server and the Global Catalog Servers.  Clients are taking an 
extremely long time to connect to mail and access resources.  None of my other 9 
facilities have this problems and the only thing different is that none of the others 
have a firewall between our two organizations.

What ports do they have to open to allow proper communications between their clients 
and my servers?
