Exchange 2007 Database Defragmentation

Last week due to an issue with the anti-spam client on my exchange server, I had to defrag the default "Mailbox Database". Below are the steps I performed to accomplish the task.

In my environment the Exchange databases are located on the D: drive.

1. Dismount the database in question via the Exchange Management Console


2. Via the command line, move to directory C:\Program Files\Exchange Server\Bin


3. Test the information Store of the server. (my server is named MailLady)
   
   isinteg.exe -s MailLady -test allfoldertests
   


4. Type the number of the database and hit Enter. Confirm with Y and then Enter again


5. If all tests pass then run an integrity check on the database
   
   eseutil.exe /g " D:\Exchange Databases\Mailbox Database.edb" /t "D:\Exchange Databases\Temp\temper.edb"
   
   
6. If that passes then run a defrag of the database
   
   eseutil.exe /d " D:\Exchange Databases\Mailbox Database.edb" /t "D:\Exchange Databases\Temp\temper.edb"
   
   
7. After that finishes then mount the database via the Exchange Management Console

By default the eseutil command creates a temporary database inside the Bin directory on the system drive. Since my Exchange Server didn't have that much free room on the system drive I had to use the /t switch to move the temp database to a drive with more room.
