Good Morning,

I am in the middle of migrating our Exchange 2010 environment to Exchange 2013 CU9.  I want to remove the General Mailbox from the volume it currently resides on and onto a new volume with more space (the volume with more space houses a database that we no longer need and will be removed).

I created a new volume and database called TempDB and then moved everything from the General Mailbox database to the TempDB database.  When I run Get-MailboxDatabase -Identity "General Mailbox" | Get-Mailbox, it just returns to a command prompt signifying that no mailboxes reside on that database.

When I run Get-MailboxDatabase -Identity "General Mailbox" | Get-MailboxStatistics, it lists all of the mailboxes that were previously on the database.  I am not quite sure why it doesn't just return to a command prompt since there are no mailboxes that reside on that database.

The other reservation I have about removing General Mailbox is that the database is still showing that it is using roughly 10GB of space.  That space is being used by the WSECU General.edb file, so I am very reluctant to remove it.  I would assume that after moving everything from General Mailbox > TempDB that the database would show as being empty.  Is this not the case?  Am I just being paranoid?  Is safe to delete the General Mailbox database?

Thank you for your time and any feedback you can provide.

Hi,

These are disconnected mailbox, when moved from 2010 to 2013 it will create new mailbox on 2013 copy contents and disconnects the existing mailbox. check the status of mailbox whether it is disconnected or not.

Thank you for the quick response Vishwanath.  I apologize as I didn't clarify better.  Almost all of the mailboxes are already moved over to the new 2013 CU9 environment.  I am trying to do some cleanup after the fact.  The mailboxes and databases in question already reside in the 2013 environment.  I should have left out the migration part in the initial post.  Sorry about the confusion.
