Exchange 2010 memory Capping

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.

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.
