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?

Our infrastructure

Site 1

3 MBX in DAG 1 [Exchange 2013 SP1] servers

2 CAS Servers behind a HLB F5

Site 2

same as above

The company has 2 Edge servers [Exchange 2010] and 2 DLP servers for each location.

Your feedback is highly appreciated

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?

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.
