We currently have a new server deployed last weekend running Windows Server 2008 R2 with Exchange 2010. The server has 32GB of RAM installed. Our clients have been reporting that the new server is slower than the previous, after investigating all i can see that may be a possible issue for performance is that store.exe is using 22GB of RAM. Is there any way to prevent this from using all this ram, its kind of weird and is causing performance issues.
Any help would be appreciated.
