After you restore a mailbox store to a recovery server that
is running Microsoft Exchange 2000 Server, you cannot connect to that mailbox
store by using the Microsoft Exchange Server Mailbox Merge Wizard (ExMerge).
When you view the ExMerge log, you see an error message that resembles the
Error opening message store (EMS). Verify that
the Microsoft Exchange Information Store service is running and that you have
the correct permissions to log on. - 0x8004011d (

This problem occurs if one of the following conditions is true
- The mailbox store that contains the System Attendant
mailbox is not mounted.
- The Recovery
Storage Group (RSG) server does not have a System
- ExMerge uses the System Attendant mailbox to connect to
To resolve this problem, make sure that the mailbox store
that contains the System Attendant mailbox is mounted on the recovery server.
Typically, the System Attendant mailbox is homed on the first mailbox store
that is named Mailbox Store
Method 1 : Mount the mailbox store that contains the System Attendant mailboxNote
By default, the System Attendant mailbox is created in the first
mailbox store in the first storage group on the first Exchange server.
- Click Start, point to
Programs, point to Microsoft Exchange, and
then click System Manager.
- If Administrative Groups are not enabled, go to step 3. If
Administrative Groups are enabled, expand the Administrative
Groups container, and then expand the first
- Expand the Servers container.
- Expand the first Your_Server
- Expand the First Storage Group
- Right-click the Mailbox Store
(Server_Name) store object, and then click
- Click OK.
- Expand the Mailbox Store
(Server_Name) object, and then click
- In the right pane, verify that the System
Attendant mailbox exists. If you do not find the System Attendant
mailbox, right-click the Mailboxes container, and then click
Run Clean-up Agent. The System Attendant
mailbox will appear and will be connected.
- Exit Exchange System Manager.
- Run ExMerge.
Method 2: Create a Recovery Storage Group (RSG) and restore a production database
- Make sure that the System Attendant Mailbox is present on
the server where the Recovery
Storage Group is created.
- The Mailbox Store that
holds the System Attendant
Mailbox should also be mounted.
- Before you
create a Recovery Storage
Group and restore
any production mailbox store to the RSG, we recommended that you make sure that
you already have a Mailbox Store on this server that has the System Attendant
On Exchange 2003, you can have one usual Mailbox store which has
the System Attendant mailbox and one RSG store. You cannot create a Mailbox
Store after the RSG store was created. Make sure that the usual Mailbox
store that has the System Attendant mailbox is created first and then create
the RSG and restore the production database to it.
- If you already created a Recovery
Storage Group on an Exchange 2003 server and restore a
production database to it, you will need to dismount and delete this RSG and
create a normal Mailbox Store first.
- You can run the Cleanup agent to force the System Attendant
- As soon as the System Attendant mailbox is generated, you can
new RSG and connect to the same .edb and .stm restore
- Connect the RSG to the related Production Mailbox Store and
then mount it.
- You should be able to use ExMerge successfully
