To move the System
Attendant mailbox:

1. Change the homeMDB attribute of the Microsoft System Attendant
object
for the server to reflect the new database. For example, if the
homeMDB value is

CN=Mailbox Store (SERVER1),CN=First Storage
Group,CN=InformationStore,CN=SERVER1,CN=Servers,CN=First
Administrative
Group,CN=Administrative Groups,CN=First Organization,CN=Microsoft
Exchange,CN=Services,CN=Configuration,DC=mycompany,DC=com and you want
to move the System Attendant mailbox to a database
called DB2 in storage group Second, change the homeMDB value to

CN=DB2,CN=Second,CN=InformationStore,CN=SERVER1,CN=Servers,CN=First
Administrative Group,CN=Administrative Groups,CN=First
Organization,CN=Microsoft
Exchange,CN=Services,CN=Configuration,DC=mycompany,DC=com The System
Attendant object for each Exchange server islocated in the
Configuration container of your Active Directory
forest.
The path to it is:

CN=Microsoft System Attendant,CN=[server
name],CN=Servers,CN=[administrative group name],CN=Administrative
Groups,CN=[organization name],CN=Microsoft
Exchange,CN=Services,CN=ConfigurationNote There are several ways to
edit
the homeMDB value. You can use the Adsiedit tool, the LDP tool, or the
LDIFDE tool. Step-by-step instructions for editing the homeMDB value
with
LDIFDE are provided at the end of this article.

2. Stop and restart all Exchange services.

3. Run the Mailbox Cleanup Agent against the original database. To
access the Cleanup Agent, right-click the Mailboxes object for the
database. After you run the Cleanup Agent, the original System
Attendant mailbox should have a red X next to it, indicating that it
is
no longer connected to an Active Directory object.

4. Right-click the disconnected System Attendant mailbox, and then
permanently delete the mailbox. Warning After you complete this step,
you cannot move the mailbox back to the original database. To move it
back, you must delete the physical database files, and allow a fresh
database to be re-created.

don't move it - just blow away the EDB/STM and the mailbox will be re-created
by itself on the new EDB you re-create.
