Mailbox Database has Multiple Copies on Same Server

Hello,

I am in the process of creating a bunch of new mailbox stores in our production Exchange 2010 environment.  I was scripting it through the Management Console and one of the add-mailboxdatabasecopy commands got hung up.  I cancelled out of it and went to look at the mailbox database via the GUI.  It only shows one copy but the database existing on the same server twice.

A report from get-mailboxdatabasecopystatus show the database existing on the same server twice one looks normal and one has three dots after the name.  An attempt to remove either copy returns a result of "unable to remove as the database has multiple entries".

Any thoughts would be appreciated.

Thanks!

use the console to check what mailboxes are mounted and their locations. see if you can identify the original one and any additonal copies. if its mounted you cannot delete it.

Locate the un-needed copy and dismount it. then remove from exchange. then delete.

"Locate the un-needed copy and dismount it. then remove from exchange. then delete."

look at the mailbox databases and work out which is the original and which is the copy.

Let's see if I can explain it a little better.

I have a mailbox store called EXEC03.  I have two mailbox servers one called VAEQMEMUP01 and the other call VAEQMEMUP02.

My desire is for an active copy on VAEQMEMUP01 and a passive copy on VAEQMEMUP02.  What I currently have... is two mounted copies on VAEQMEMUP02.  Here is the output from get-mailboxdatabasecopystatus:

[PS] C:\Windows\system32>Get-MailboxDatabaseCopyStatus -Identity "EXEC03"

Name                                          Status          CopyQueue ReplayQueue LastInspectedLogTime   ContentIndex
                                                              Length    Length                             State
----                                          ------          --------- ----------- --------------------   ------------
EXEC03\VAEQMEMUP02...                         Mounted         0         0                                  Healthy
EXEC03\VAEQMEMUP02                            Mounted         0         0                                  Healthy


[PS] C:\Windows\system32>

As advised above, you need to identify the one you dont need. I could guess the one with the dots after it as that is likely to be the copy but you'd be best to check before deleting it, just in case.
Check the file creating times or any settings that can help you work out which to keep.

Once you are happy to remove one, use the command below:

Remove-MailboxDatabaseCopy -Identity server\name -Confirm:$False

I'd recommend using the console though as it is less likely you'll get the wrong copy.
EMC > Organisation config > mailbox > database management tab
Select mailbox you want to work ok. click 'databse copies' righ click the one to get rid of and then 'remove'

I actually had to remove it via ASDI.  Once i did that and waiting for replication, all was well.
