Hi ,
I have been experiencing a strange problem lately , all of my outlook users get disconnected and goes to "Trying to connect"status come back online after i restart cas servers. meanwhile owa & mobile users are able to use their emails without any disconnection. I have been searching for the logs but i haven't found any solution yet . Please help me to identify the issue. server address is pointing to Windows NLB interface CAS servers.
also i have checked port 443 is not blocked by Firewall.
PS:- I'm using Microsoft exchange 2013 Enterprise ,2 cas servers & 2 mbx servers on windows server 2012

that would probably happen when the RPC service is going into hung state, monitor the server resource utilization.. check for mailboxes with the highest number of the folders and items.. that could be one the reasons....

I also noticed that i get below error quiet frequently.
This is all started all of sudden when owa,ECP,outlook& powershell was not accessible few weeks back. The reason been SSL certificate binding was lost on IIS backend & frontend Website.
and i followed below link to rectify.but since then once in a few days just the outlook users goes to "Trying to connect" state .(meanwhile OWA mobile users can access email without any issue) .I just cant figure it out what it is.
