SYMPTOMS
A simple Messaging Application Program Interface (MAPI) application passes a Double-Byte Character Set (DBCS) string to the MAPI call MAPIResolveName. MAPIResolveName fails when a two-byte DBCS character contains 0x5b or 0x5c as one of its bytes.



CAUSE
A supporting routine used by MAPIResolveName was not written to properly handle DBCS strings, and mistakenly interprets the bytes 0x5b and 0x5c as '[' and '\' respectively.



RESOLUTION
To resolve this problem, obtain the latest service pack for Exchange Server version 5.5. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

Component: MAPI



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