Mailbox Store attribute modification

Modifying the Mailbox Store attribute means moving a user mailbox from one mailbox store to another.

You can move a mailbox either within the same Exchange server or to a different Exchange server in the same domain. For more information about moving a mailbox from one mailbox store to another, see the Microsoft Exchange server documentation.

When you modify the Mailbox Store attribute, the value of the homeMDB attribute changes because the user mailbox moves from one mailbox store to another. The following example illustrates changes in the value of the homeMDB attribute, when you modify the Mailbox Store attribute.

For example, a user account with the name Thomas Daniel exists on the Active Directory (domain name is ibm.com®). Consider Thomas Daniel has a mailbox in the First Mailbox Store of the Exchange server (ps2330) as shown in the following figure.

Figure 1. Exchange server organization tree

The value of the homeMDB attribute is:

cn=First Mailbox Store,cn=First Storage Group,cn=Information
 Store,cn=ps2330,cn=Servers,cn=First Administrative Group,
cn=Administrative Groups,cn=First Organization (Exchange),
cn=Microsoft Exchange,cn=Services,cn=Configuration,dc=ibm,dc=com

When you move the mailbox of Thomas Daniel from First Mailbox Store to Second Mailbox Store, the value of the homeMDB attribute changes. The value is now:

cn=Second Mailbox Store,cn=First Storage Group,cn=Information
Store,cn=ps2330,cn=Servers,cn=First Administrative Group,
cn=Administrative Groups,cn=First Organization (Exchange),
cn=Microsoft Exchange,cn=Services,cn=Configuration,dc=ibm,dc=com
