XFOR: DXA Appends 001 at End of Display Name in MS Mail GAL |
The information in this article applies to:
-
Microsoft Exchange Server, version 5.5
SYMPTOMS
The directory synchronization service (DXA) appends the characters 001 at
the end of the user's display name when performing directory
synchronization between Exchange Server and Microsoft Mail under the
following conditions:
- Deletion and creation of mailboxes with the same name occur in the same
cycle of the dirsync.
- Delete transaction reaches the dirsync server before add
transaction.
CAUSE
When the above steps are performed, the code compares the full name of the
added user with that of the deleted one and decides that the display name
needs to be unique. The postoffice comparison fails because the deleted
user's e-mail address is a NULL string, and the code is not handling this
condition correctly. As a result, 001 is appended at the end of the display
name in the GAL.
RESOLUTION
To resolve this problem, obtain the latest service pack for Exchange Server
version 5.5. For more information, please see the following article in the
Microsoft Knowledge Base:
Q191014
XGEN: How to Obtain the Latest Exchange Server 5.5 Service Pack
The English version of this fix should have the following file attributes
or later:
Component: DXA
File Name Version
----------------------
Dxa.exe 5.5.2393.0
STATUS
Microsoft has confirmed this to be a problem in Microsoft Exchange Server
version 5.5.
MORE INFORMATION
The problem described above is relevant only in cases where the following
registry entry is "0":
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeDX
\Unique Display Names
For more information about this registry entry, see the following article
in the Microsoft Knowledge Base:
Q166545
XFOR: Exchange 5.0 DXA Appends 001 Only When Needed
This article states that when the Unique Display Names registry entry is 0,
001 is not appended if NETWORK/PO is different, even when a user with the
address type of MsMail and the same name is dirsynced. However, if dirsync
is performed under the conditions in the SYMPTOMS section above, 001 will
be appended at the end of the display name.
