Hi All,

I'm new to the Zen Loadbalancer and I'm having some issues getting is working 
as part of an Exchange 2007 solution.

I'm try to use v2 (stable) as a solution to balance and terminate HTTPS 
connections to an Exchange 2007 environment. Everything is working great for 
OWA (Outlook Web Access), but it's not working for OA (Outlook Anywhere - RCP 
over HTTPS).

Here's what I know:


-          I'm using a self-signed certificate for testing, which was created 
with OpenSSL and I have added this to my Trusted Root Certificates store on the 
machine I'm testing from.

-          OWA (Outlook Web Access) works great, the certificate shows 
correctly in the browser (IE 9), so no problems there.

-          When I try to connect using OA (Outlook Anywhere), I just get a 
response from Outlook saying 'Server Unavailable'.

-          In the configuration for the Farm, I have the RPC extensions enabled.

To try and troubleshoot this, I've used Wireshark to do a packet trace of a 
working solution (which uses MS ISA Server for the HTTPS termination) and from 
Zen.

The main difference that I can see is that with Zen Loadbalancer, I get a TLS 
"Encrypted Alert 21' messages and then the connection is reset.

I could really using some help in trying to troubleshoot this, as I'm keen to 
use Zen to replace MS ISA Server, but need to resolve this OA (Outlook 
Anywhere) issue.

So any pointers on:


-          Could it be the Certificate?

o   It is self-signed, but this works fine for OWA and is trusted on the 
machine I'm testing from...

-          Is there some logging that I could enable in Zen to understand and 
troubleshoot the problem better?

-          Has anyone else experienced this problem?

-          Could this be a Bug? (It's much more likely something I've done 
incorrectly)

Any help would be greatly appreciated. I'm happy to supply more information if 
it's required.

Kind Regards,

Graham.
