Question : Allow OWA access for Internal Users through ISA 2006 Server

Hi,
Please assist - we have ISA 2006 standard installed. (New install)
When the domain client has the ISA server set as the proxy and we try and acces our internal Webmail site (OWA)

https://webmail.company.com

The site is being blocked witha failed connection attempt

Log type: Web Proxy (Forward)
Status: 10060 A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.  
Rule: Webmail Access

What am I doing wrong with the webmail access rule?

Thankyou

Answer : Allow OWA access for Internal Users through ISA 2006 Server

You do not use ISA or any publishing Rules to get to the internal OWA when using Clients that are already behind the ISA.

You have to run Split-DNS so that the Internal OWA resolves tot he Private LAN IP# when coming from a LAN Client.
