SUMMARY
=======

You may find that the database size does not shrink after you delete several
mailboxes and run an offline defragmentation.

MORE INFORMATION
================

The database file sizes will not shrink after mailboxes are deleted or removed.
The data will be deleted and the space will be reused, but the Exchange Server
computer will not reduce the file size online. To reduce the file size, it is
necessary to take the system offline and run an offline defragmentation on the
Priv.edb database. If the services are stopped immediately after the deletion is
finished, the file size may not be reduced by the offline defragmentation
process. This is because, when a mailbox is deleted, it is only marked for
deletion. Data deletion is done by a background thread and space is not freed up
until after the background process has deleted the data. To reclaim the space
after the deletion of several mailboxes, wait for at least ten minutes before
stopping the Information Store service. Then defragment the database offline
using the command ESEUTIL /d.
