Disconnected MBs in exchange

wannabecraig asked
I've moved all mailboxes to a different store with the intention of deleting the origination store.
This is just part of routine maintenance. The intention was to unmount the original store and remove it.
However I've noticed that there are still some MBs registering in the origination store as well as the new one.
Is this still save to unmount and remove?  

They are in the disconnected mailbox section of the console but  I dont know if it's dangerous to remove the ebd or not.
Watch Question

If you don't want the disconnected mailboxes then remove them and then remove the store and database.
before removing the store/database you have to move all the mailboxes to other store/database.


The problem is that I did move the mailboxes to the other store, they show up in the other store.
But they  still show up in the Exc Mgt Shell command: "Get-MailboxStatistics -Database "mailbox"| Select DisplayName, ItemCount, TotalItemSize | Sort-Object TotalItemSize -Descending" command for the old store too.

I'm just worried that there is some issue.
Check the move request.
Also wait for some time for the replication to happen and then check.
What about the EMC is it showing in the mailbox database or other database?
exchange version?


Move request is complete and cleared.
Exchange version is 2010.
The server has been like this since last week so I imaging replication has happened.
The EMD is showing the mailbox in the new database yes.
I dont have the option to do anything with the disconnected MB except reconnect.
Should I reconnect them to the new store?
You can't use the EMC to permanently delete a disconnected mailbox. Please follow the technet link.
If you want those mailboxes then you can reconnect and move them to new store.



When I rujn this command: Get-MailboxDatabase | Get-MailboxStatistics | where {$_.DisconnectReason -ne $null} | ft displayname,database,disconnectreason -auto It tells me that the reason is a 'soft delete'

How can I reconnect them to the new EBD?


I dont want to delete the mailbox. I was moved to another mailstore, there are just leftovers in the original one.
When I try to connect it to the new store is tells me that it's already connected.

If the mailboxes have been moved successfully and users can connect to them and they still appear on the other server it is usually due to a replication delay with active directory. From the mailbox database (original database) have you tried to reset the Info store service and then check the status again?

When a mailbox move happens its actually not moving the mailbox but copying it. If it gets copied successfully then the mailbox on the original source server is purged.

You may also want to check and make sure that your AD replicaiton is operating properly.  Using the following commands
repadmin /replsum
repadmin /showrepl

Also use dcdiag /v to check health of the DC's in your environment.

Please read this.

Soft-deleted mailboxes: When mailboxes are moved from a Microsoft Exchange Server 2010 Service Pack 1 (SP1) database to any other database, Exchange doesn't fully delete the mailbox from the source database upon completion of the move. Instead, the mailbox in the source mailbox database is switched to a soft-deleted state. oft-deleted mailboxes are retained in the source database until either the deleted mailbox retention period expires or until the Remove-StoreMailbox cmdlet is used to purge the mailbox.


You can wait till the retention period expires or Remove-StoreMailbox to delete soft-delete mailbox using https://technet.microsoft.com/en-us/library/gg181092%28v=exchg.141%29.aspx

First try this on a test mailbox.


So if I use this command for the original DB, it wont delete their data from the ebd they've been moved to?


Sorry, this command:
Remove-StoreMailbox -Database maildatabase -Identity "Username" -MailboxState SoftDeleted
Yes, it will delete Soft-deleted mailbox not the original moved one.
