ESEUtil to Defrag an Exchange 2010 Mailbox Database

A garden is a complex of aesthetic and plastic intentions; and the plant is, to a landscape artist, not only a plant – rare, unusual, ordinary or doomed to disappearance – but it is also a color, a shape, a volume or an arabesque in itself. – Roberto Burle Marx



How To use ESEUtil to Defrag an Exchange 2010 Mailbox Database

We start this process by first opening the Exchange Management Shell and navigate to the folder containing the database file.

We then dismount the database

[PS] E:MailboxAB>Dismount-Database <name of database>

We now run ESEUtil to defrag the file using the /d switch to defrag

[PS] E:MailboxAB>eseutil.exe /d .<database name>

When completed we mount the database again.

[PS] E:MailboxAB>Mount-Database <database name>

Please see the following screen cap for refrence

And as always be sure that you have a backup that you can use for recovery if something goes wrong during the defrag.
