The size shown for EDB and STM files will never decrease unless you do an offline defrag. Under most circumstances, an offline defrag is unnecessary and not recommended. Check the Application event log for event ID 1221. Those will show you how much free space you have within the store files.

My store is almost 14.4 GB. Since SP2 is not yet released, I may end up in exchange store crossing 16 GB limit. To avoid storage limit problem, I moved some of my mailbox of server store to personal folders of user to reduce the information store size. When I checked store after moving, the size remaining same (ie priv1.edb). Some of my friends said it will reduce once maintainance of mailbox is run but inspite of doing it, no change in reduction of size. Can anyone help me to solve this issue because I am in fix due to storage limit. raju
