I have a load balanced pair of ISA 2006 ENT servers in a unihomed configuration. The ISA servers are in the DMZ and my Barracuda Message archiver is in the LAN. I have several web sites published using SSL as well as Exchange services working fine.
However, I cannot get the Barracuda Message Archiver working properly when publishing it. I DO have the web interface for this appliance working flawlessly, people can login and do whatever they need to. The problem is with the Outlook plugin. I can authenticate the plugin on each outlook client but as soon as I choose to use it's features (like search the archive for email) it crashes.
The moment this crash happens the ISA server logs the following generic error:

The Barracuda plugin is clearly using SOAP but I am not sure if that is a problem or not since the protocol is just https.
I have bypassed the ISA Server and the problem dissapears. Hopefully someone on here has dealt with this and can point me in the right direction.
