My New Exchange Server is taking a lot of memory

Hi Everybody,

i have just built a new exchange server 2010 in a VMWARE environment.  I created 3 different virtual drive 1) C drive for the OS 70 GB, 2) D drive for the data 200 GB( Information Store), 3) F Drive for the logs  100 GB. I assigned to this server 12 of mermory.It seems to work great but today i was checking task mananger and i noticed that  in the Performance Tab the Physical memory  Usage is 11.3 GB.  On the bottom of task manager it says Physical Memory: 94%.
IS THAT RIGHT ? i don't think is good that a new server runs at 94 %. should i add more memory? it will be very easy because i am in a Virtual Environment. Is that normal that Exchange use all this memory.I noticed one more thing. Under the Processes Tab in the Image Name Colum the store.exe is really high compare the other things. it uses something 6,866.332 when any other items uses less than 1,000.00. thank you very much for your help.

Exchange will take any memory that is available - it's perfectly normal.

Store.exe is the information store process which handles mailboxes.

Exchange 2007 / 2010 will use as much memory as you can give it.  This is by design.

My 24gb server has Exchange chewing 17gb of RAM.

Nothing you can do to this on Exchange 2010 that I have found yet to limit the amount.

Exchange 2007/2010 will use all available memory off the bat but will give it up as/if other applications require it. This can be changed the same was it was able to be done in 2007 if I am not mistaken. I haven't tried in 2010 yet but here is how to do it in 2007.
