Hi, I have MS-Exchange 2007 clustered environment in which 2 CAS servers and HT servers are configured using MS NLB clustering to pass the request. We have written some piece of java code which have tested completely at standalone Exchange Server environment and it is working fine. We are using WebDAV protocol and Http Client for performing all operations. Now, we need to connect with MS-Exchange 2007 NLB environment. Please do help us as the requirement is urgent for us. I will appreciate if you provide us any kind of help regarding this issue.

I would ask in the dev forum: http://social.technet.microsoft.com/Forums/en-US/exchangesvrdevelopment/threads
