Good Morning,
Last month we migrated from Exchange 2007 to Exchange 2013. From time to time, but mostly in the morning the server has a 100% cpu use. And then every outlook client gets disconnected. And we have absolutely no clue where it's from.
sometimes the system process or RPCClientAccesServices or noderunner has a high cpu,
I know that exchange 2007 had a tool Exmon but it's not working with exchange 2013. Is there a similar tool to check this? And what can we check why this is happening?
Specs.
It's running on vmware Esxi 5.5
windows server 2012r2
32Gb ram
4 CPU core
11 databases
