The specific ports required are basically all of them. Especially those
above 1024 TCP/UDP (in both directions. )

You *can* narrow it down by setting static ports like this:

You should also be aware of the way that Exchange tells Outlook to find a
GC.  You may want to investigate the closestGC registry key for Outlook
(called something like that).

Subject: [exchangelist] Firewall settings for MAPI Outlook 2003 and Exchange



We currently try to make Outlook 2003 work via MAPI through a Firewall. Yes,
I know, it is a bit unusual...

The DC (with GC) is on the same network as the desktops, so it's just the
Exchange server that we need the port settings for.

The server is a Windows 2003 server running Exchange 2003 standard edition.



Searching with google gave me a lot of answers, all with ISA server
involved...But no specific port settings.

Does anyone know where I can find those?


Kind regards,
