This article was previously published under Q239065





SYMPTOMS
When you configure Microsoft Exchange Mailbox Manager on a server running Exchange Server 5.0 Service Pack 2, and click the Server Selection tab, no servers are listed, and you may receive the following error message:

LDAP Authentication method is not supported



WORKAROUND
If you have a computer running Exchange Server version 5.5 in the site, you can configure Mailbox Manager from that server.

If you do not have any Exchange Server 5.5 computers in the site, you can still run Microsoft Exchange Mailbox Manager on the 5.0 computer. Cleanup is performed on mailboxes on that server, although you cannot see the server on the Server Selection tab.



STATUS
Microsoft has confirmed that this is a problem in Microsoft Exchange Server version 5.5 Service Pack 3.



MORE INFORMATION
This behavior also affects the retrieval of hidden mailboxes.
