cwr -> ISA & Microsoft Outlook (27.May2004 10:37:00 AM)

Hi,

I have ISA server setup on a colocated server, running Exchange & Active Directory etc. I'm wondering if anyone knows what ports I need to allow on ISA Server so that users can use Microsoft Outlook?

Basically, one machine is running ISA Server & Exchange, but when users VPN to the machine (can do this ok, have tested), they try open outlook and it brings up the 'Your Microsoft Exchange Server is unavailable' in Microsoft Outlook.

Hi cwr,

If you are connecting to the server via VPN, you shouldn't need to open any ports.

Once you have successfully connected via VPN can you ping the server by name?

Hi,

I opened up 135 & 139 (tcp), 137 and 138 (udp) and it seemed to start working. The DNS was also mumbled, adding an entry in the hosts file for the 192.168.0.x address seemed to kill any problems I was having.

I'm not sure that opening those ports on the ISA server is recommended!
