My Database is 700GB
Freespace is only 60 GB

I have read about the ESEUTIL  / D   to defrag the drive, but my understanding is that I need more space.

Any suggestions or answers on the proper way to compact my database?

Hello,

Is the 60GB free space on the disk or inside the database? The database file size on disk never shrinks. When you delete items, it frees up whitespace inside the database. Exchange will consume any available whitespace before growing the database file on the disk. You can check how much available whitespace you have by running this command:

Get-MailboxDatabase -Status | ft Name, Databasesize, AvailableNewMailboxSpace -Auto

Deleting mailbox items and/or whole mailboxes doesn't immediately free up space. There is a deleted item retention and a deleted mailbox retention setting on each database. Items are not purged until the time set on these expires. You can speed up the purging by decreasing these values.

The only way to decrease the size of the database on disk is to run ESEUTIL and only if you have whitespace inside the database. Generally, I wouldn't recommend doing this as it will cause downtime and it isn't without risk. You also need disk space available that is equivalent to at least the current size of the database. You are better off creating a new database and moving all your mailboxes to the new database. This will be the least disruptive to users and the safest method. You still need disk space equivalent to the size of the database on disk minus the whitespace in the database. Even this process isn't worth the hassle unless you have a significant amount of whitespace.

JJ,
To begin, I truly appreciate your response.
To answer your question my 60GB is free disk space on the partition that the Exchange Database resides.
I notice, that I seem to have an unstable Exchange server when my Disk Free space is below 10% of the total size of the Exchange Database.  So, freeing up space (175GB of deleted/purged) users was my intention.

I will take your advice and add some additional storage , create a new database and move the users over so I do not have any down time.

Thank you again for the Whitespace command, and your help.   I truly appreciate it.

-Eric
