memory optimization for Exchange 2003
I'm running Windows 2003 Standard with Exchange 2003 32 bit. I have 4 GB's of RAM in my server. I recently optmized the memory settings for my Exchange 2003 backend server. All event ID's pertaining to non-optmized memory have gone away. What I did notice is that my system is only using a total of 1.6 GB's of RAM. The store.exe process if only using 1.03GB's of RAM. I have 65 users on this server and the total private info store size is 55 GB's. Shouldn't Exchange be utilizing more memory? Should I force the store.process to use more memory?

the store.exe will take memory to reach the required warm state as it want, Exchange 2003 has some of memory behavior in Exchange 2007, but it will address only 3 GB of memory, 65 users is very small number and 4 GB is fine
Oups ! Sorry "gopher_49D" !
I think this amount a memory is good and I suppose you have only Exchange installed on the server !
I've seen almost same results on servers running Exchange and File & Print services and SQL and IIS in a 50-60 users environment with 3 Gbytes of RAM and only 1,8-2 (when the back up was running ) of memory used, so I believe you are OK !

Run the Exchange Best Practice Analyser:

It will highlight any other things you should fix for better performance etc, but for 55 users that amount of RAM usage seems fine.
Do you have /3GB and /USERVA=3030 in your boot.ini file?

I've ran the Exchange Best Practce Analyser and all seems well. I also have the /3GB switch utilized.. I just figured since I have 4 GB's of RAM Exchahge would take advantage of this better. Since this is a virtual machine I figure I can go ahead and pull 1 GB away from it. I actually have 2 x VM's on 2 x different physical hosts. I think I'll go ahead and pull 1 GB from each of them and save me 2 GB's of memory that I can allocate to another VM.
i would recommend leaving some memory for exchange, exchange has some other services other than store.exe that requires memory, give the exchange 3 GB
In case you have anti-virus installed on the server to exclude Exchange's folders !
