I saw that but could not understand.
 
It says "The database "First Storage Group\FSG-Silver-2" has 10484 megabytes of free space after online defragmentation has terminated. " 
 
What does this mean? given that all users mailbox size comes to 8 GB on this database and  the total database size is 28 GB , can you please explain.

If you look at the event 1221 it tells you how much white (free) space there is in that database.

Thank you all for your response!
 
In fact database maintenance is enabled and there are 1221 events, I did not search it properly.  To calculate the amount of space occupied by the users in a particular database I summed up each mailbox size and it is 8GB but the database is 28 GB.
 
This is a new cluster setup and I migrated user mailbox from old setup( old is also exchange 2003 SP2), hence I expected it do away with any white space. But the size of the database remains same. That is the reason I wanted to know if there are any tools to first check to see that database really requires offline defrag, this tool should run when the database is online.
 
Can I run ESUTIL space dump when database is online?? Is it recommended to do so? Will this help me in taking a decision ? Please advice.

Even u can plan for DB consolidation for eliminating the white space in the database. Procedure for doing this is as follows.
Move all the mailboxes to different store.
Dismount the store.
Rename the database to some other name.
Mount the store.
New database will get recreated.
Delete the old renamed database.
Move all the mailboxes back to the original store.

Configure database maintenance and you will start getting 1221s.

Hi,
 
Few of my exchange database is un-necessarily high, it is showing 29 GB though it has only 200 users each, other databases are showing only 5 to 7 GB. How do I decide about running offline defrag or not on this database. I am not even getting any 1221 events also. Because of the size of the database my backup is taking longer.
 
I use exchange 2003 SP2 on windows 2003 SP1. Please advice.
 
Regards
Praveen R
