This is a very crude script to defrag (using eseutil) Exchange mailbox databases.

The script takes the database name as a mandatory parameter. It then dismounts the database, checks whether the database state has been shutdown cleanly, performs the defrag, verifies the state again, and finally, mounts it again.

Note that this is an offline process. The specified mailbox database will be offline, meaning that all mailboxes in the database will not be accessible until the process has been completed.

Use with caution!

This script has not been tested extensively and does not account for everything that can go wrong. I merely provide it as a good starting point to extend the script to something better and more useful.

Use with caution!
