Exchange 2010 memory Capping
You will have tough time if exchange servers has high memory utilization. In exchange 2010 you have to modify both msExchESEParamCacheSizeMax and msExchESEParamCacheSizeMin value to get it working. Really that is the trick!!!
Update Note :- msExchESEParamCacheSizeMax effective effective only when msExchESEParamCacheSizeMin value is also configured. And Exchange Server
restart is required after changes.
Then restart Information Store Service or restart exchange server if possible.
First of let us do calculation
Exchange 2010: 4 GB = 4.194.304 KB / 32 KB => 131072
Define Min and Max Value
Min – 1GB: msExchESEParamCacheSizeMin = 32768
Max – 4GB: msExchESEParamCacheSizeMax = 131072
You must adjust above given values to suit your server environment.
Start -> ADSIedit.msc, or navigate to Start -> All Programs -> Administrative Tools -> ADSI Edit.
Then go to Configuration -> Services -> Microsoft Exchange -> ”Organization Name” -> Administrative Groups > ”Administrative Group” -> Servers -> ”Server Name” -> InformationStore
Then restart Information Store Service or restart exchange server if possible.
