Unable to see reclaimed disk space on a database that was recently updated

Hello Experts,

I have a customer who recently performed bulk mailbox move from a source database to a target DB. The total amount of mailboxes and the expected size to be recovered was 30 GB, and unfortunately the source database still shows the same space

I ran the following PowerShell to check available free disk space on the DBs, and I do not see a difference

Get-MailboxDatabase -Status | Sort-Object AvailableNewMailboxSpace -Descending | Format-Table Name, DatabaseSize, AvailableNewMailboxSpace

The mailboxes were migrated this Monday, and as of today, I am unable to reclaim disk space on the source database

Any ideas?

Please, understand that an offline defragmentation of my source database is not an option here, because I will have to dismount the DB

Is there another option to reclaim disk space on a Exchange 2013 database?

Delete and recreated old DB again is the best way to reclaim the space. DB size won't reduce after mailbox move. Offline defrag is not recommended for DAG db's. Offline defrag also creates new db. You can confirm from db signature.

Thanks Amit,

Is there a Exchange 2013 SP1 CU update that fix the issue of reclaiming whitespace on a Exchange 2013 database that is part of a DAG?

No hotfix required to reclaim disk space. Recreating new DB is the best way.
