SYMPTOMS
After a mailbox is moved between two servers in the same Exchange site, and the client profile is updated properly by the original Exchange Server computer, Exchange Client cannot connect to the new server using the Domain Name Service (DNS) fully qualified domain name (FQDN) of the new Exchange Server computer when the original server is offline.



CAUSE
After a mailbox is moved successfully between two Exchange Server computers in the same site, the Exchange Client connects to the original server and, at that time, the client profile is updated properly. After the client profile is updated, any subsequent logon to the mailbox does not require the original server.

During the profile update, several registry keys are updated. One of these registry keys holds the FQDN for the new server. However, this key does not get updated during the client profile update. As a result, a user cannot access the mailbox if DNS is the only name resolution mechanism and if the original server is offline.



WORKAROUND
You can work around this problem by manually updating the profile by performing checkname:
 * 1) Click the Mail and Fax icon in Control Panel.
 * 2) Select Microsoft Exchange Server.
 * 3) Click the Check Names button.



STATUS
Microsoft has confirmed this to be a problem in Exchange version 5.0. This problem has been corrected in the latest U.S. Service Pack for Microsoft Exchange Server version 5.0. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):

MORE INFORMATION
The key below holds the profile information for an Exchange Client:

  HKEY_USERS\\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\\13dbb0c8aa05101a9bb000aa002fc45a

The following values are used to store the server name:

001e6602 stores the NetBIOS computer name where the mailbox is located and is updated correctly when the mailbox is moved.

001e6608 stores the TCP/IP address, the NetBIOS computer name, or the DNS FQDN used to create the initial profile. It is not updated when the mailbox is moved or profile checkname is performed.

101e6613 stores network names according to MSRPC binding names (obtained from network address attributes on server objects in DSA). It is not updated when the mailbox is moved but is updated when profile checkname is performed manually.

The value 101e6613 is the one that needs to be updated to make sure that the FQDN for the new server gets updated in the profile.
