Ex55 Database name Home-MDB


In principle, this is the specification of the home server, whose distinguished name leads to the site name. The site is the one in which the mailbox is stored in - and the MDB is representing the database kernel of an Exchange 5.5 server.


The distinguished name of an exchange database object always starts with cn=Microsoft Private MDB, after that the DN of the regarding server follows. An example for an Home-MDB would be:


cn=Microsoft Private MDB,cn=SRV1,cn=Servers,cn=Configuration,ou=Site1,o=CERROTORRE


Please note that server objects for Exchange 5.5 servers are always stored in the 'Configuration' container beneath the site. You should change the Home-MDB attribute only if you have moved the mailbox to another Exchange server. This can be done with the Exchange 5.5 admin tool in the 'Advanced' tab of the mailbox object. However, mailboxes in Exchange 5.5 environments can only be moved intrasite and never between two different sites.


Home-MDB is an operational attribute which is not automatically retrieved by a GetObject() or an GetInfo() call. You can load such attributes into the object property cache by explicitly calling GetInfoEx(). Read more about this technique in the topic 'Reading object attributes' here in the SelfADSI tutorial.
