Do nothing ... or add more RAM - it will use more RAM.

Exchange is designed to use every available bit of RAM but also to give it up if it's needed for something else.

Thanks for the quick response.  Then how can I monitor for a real memory issue.  We usually monitor memory that if it goes above 80% to notify us.  Based on this, what are my monitoring options?

Thanks

While that is a very large amount of RAM to be in use, Exchange by design will use as much RAM as physically possible.

Hi,

Run Perfwiz for exchange 2007, basically the scripts to start gattering the data

in cluster admin  take the store offline and then restart it
when it comes back online it will release all the memory and start clean

next   add more memory to all servers in the cluster

or  have users clean there mailboxes out.  make sure deleted items are deleted and sent items they don't want deleted also, if this is not an option  set up archiving on the users pc's and archive older items
