Reducing MS Exchange 2007 store.exe memory usage

We have one Exchange 2007 on Windows Server 2008 with 32GB memory. There are only 10 user mailboxes and the server report 30GB of memory used, with store.exe using 25GB.

Each user mailbox is about 10GB. Does this point to some problem? is store.exe using 70% of the memory because users have all the emails in the Inbox instead of subfolders? One user had 7,000 emails in Inbox, the rest I suspect behave the same way.

Any suggestions, comments welcomed. Thanks.

The store.exe service is designed to take up any spare memory in order to carry out Exchange related tasks, and then release it when other processes require it.  It is quite normal for it to be eating up the memory.

However if you think that it is not deallocating memory and causing the server to run slow then there may be an issue, and further memory checks using performance monitoring may be needed.

As an aside 10GB mailboxes are large on average and this will increase exchange overhead, and this may cause you an issue when moving/restoring mailboxes however the lack of subfolders won't make a difference.

When you install Exchange, a dll is installed called exchmem.dll.  This becomes the new memory manager for your system.  This dll allocates all available memory to store.exe by design.  As other applications call for memory, this dll will re-allocate memory as needed for the these other applications.  This is to be expected and is actually as designed by Microsoft.
