SYMPTOMS
The sender display name may unexpectedly contain backslash characters in an e-mail message that is sent from a Microsoft Exchange Server 2003 organization. For example, the display name Administrator (HQ) may appear as Administrator \(HQ\).



CAUSE
This problem may occur when one of the following conditions is true:  A Microsoft e-mail client program or a third-party e-mail client program does not remove backslash characters that Exchange Server 2003 adds. Exchange Server 2003 adds backslash characters when the following conditions are true:  The server that is running Exchange Server 2003 has hotfix 886757 applied. This hotfix is described in the following article in the Microsoft Knowledge Base:

886757 A sender's e-mail address appears to a recipient as two distinct addresses if the sender's display name contains a comma and extended characters in Exchange 2000 or in Exchange 2003

 The RFC2047Compliant registry value is set to &quot;0&quot; as described in that article. The display name contains non-US-ASCII characters.

In this case, Exchange Server 2003 may encode the display name incorrectly. Therefore, backslash characters that Exchange Server 2003 adds to the display name may be displayed in a Microsoft e-mail client program or in a third-party e-mail client program. A third-party e-mail client program does not remove backslash characters that Exchange Server 2003 adds to the display name to mask certain US-ASCII characters. This particular issue occurs only when the message is viewed in a third-party program.</ul>
