Open port range on Exchange Cas array object to enable Outlook Anywhere
Hi
Using Exchange 2010 SP3 and LTM 11.6.0
Outlook Anywhere is currently not working externally. The reason is it tries to proxy connections to the Excahnge CAS array object on port 6001-6004. The cas array is load balanced virtual server, part of an application service on LTM, and these ports are never configured and will be rejected.
Changed some Exchange configuration, the EXPR Outlook provider, to use a internal server and it now works internally only.
I wonder if something is configured wrong since i cant find many with the same issue. Found some but they never figured out what caused the issue and the solution was to not use HLB for RPC/MAPI.
So, I want to: 1. either open the port range. 2. somehow make Outlook anywhere connections proxy directly to CAS servers Explanation; make this: mail.hostname.com/rpc/rpcproxy.dll?CASARRAY:6002 Into something like this: mail.hostname.com/rpc/rpcproxy.dll?Exchangesrv:6002 3. help with finding my miss-configuration :)
Used fiddler to verify this is the issue.
