Hi,
We have 5 CAS 2010 behind the load balancer. Everything works fine. SOmetime we are getting event ID 7011 in system logs with below description on any of the one of CAS server and user's outlook 2010 get disconnect.
"A timeout (30000 milliseconds) was reached while waiting for a transaction response from the MSExchangeAB service."
"A timeout (30000 milliseconds) was reached while waiting for a transaction response from the MSExchangeRPC service."
We have statically configured end point mapper port 8000 & 8001
What are the factors which affecting this issue?
Is this issue related to Exchange 2010 SP3 or Windows 2008 R2?
Thanks
