Excessive virtual memory usage on Exchange server

Virtual memory
I'm currently running a Win 2K3 SBS Exchange server with 3GB memory. Over the last few months I have received errors in the event viewer regarding virtual memory fragmentation. The virtual memory increases to about 6GB. I restart the Exchange services, this releases the memory used. About 700mb of physical memory is used by store.exe and it stays at that figure. During the day the virtual memory is stable but checking the following morning it has increased by up to 1.2GB at a time. The Exchange database is stable and i have no other issues. I have a hunch that the online defragmentation is causing this. I have a ‘First storage groupmailbox store’ that states 5093MB free in the event viewer. Would an offline defrag be recommended or could this be something else?

The best remedy you can do is to remove the excess virtual memory set to your computer server. You can do this by right clicking the Computer or My Computer, click the Advanced Tab or link, under the performance click the Settings, click the Advance Tab, then finally click the change at the bottom. From that setting, you can set your preferred amount of virtual setting for your computer.
