Question
Thursday, July 5, 2018 8:39 PM
Hello people,
Just trying to figure this out. I'm trying to move some large mailboxes to a new Database in the same Exchange 2016 DAG and I'm getting the following status: StalledDueToSource_MdbCapacityExceeded
I've googled some people who had a similar issue with Exchange Online and separating the mailboxes from the batch fixed the issue for them. Though their status was StalledDueToTarget. I'm only running a batch with a single user at the moment.
Any ideas?

Hi Brian,
From the error message, I recommend to check the free space of disk and mailbox database.
Get-MailboxDatabase -Status | select Name,DatabaseSize,AvailableNewMailboxSpace
By default, database size limit for Exchange Server Standard Edition is 1024 GB.
Also, check the size of disk, and ensure there're available disk space for mailbox migration.
Best Regards,
Allen Wang

Hey Allen,
So I've got about 110 GB of available disk space. The Database that I am trying to migrate from is currently 1.032 TB and has 15.28 GB of AvailableNewMailboxSpace. I'm going to try and migrate a mailbox that is under the 15.28GB available space limit to free up enough space to migrate a larger mailbox.
I had previously changed the registry key in this procedure in order to remount the database for the client because it hit the default limit of 1TB.
I'm just wondering why, after increasing the limit to 2 TB that I still only have 15.28GB of available space. The Information Store was cycled after the registry change...

Even when attempting a mailbox move for a mailbox with size under current AvailableNewMailboxSpace the mailbox move request stalls due to source MDBCapacityExceeded.
