SYMPTOMS
When using a one-off X400 address to send a message from a Microsoft Exchange user to a Microsoft Mail recipient (that is, an address in the form "c=us;a= ;p=ms;o=EX1; dda:ms=ms/po1/admin"), the Information Store produces a nondelivery report (NDR) back to the sender.



CAUSE
The Information Store incorrectly parses the single forward slash as an address delimiter, thereby causing the address to seem invalid.



WORKAROUND
To work around this problem, do either of the following:


 * Use double forward slashes between the portions of the Microsoft Mail address included in the DDA value. -or-


 * Obtain the hotfix mentioned below. With the hotfix, the Information Store handles the single forward slash in the DDA value correctly, and the address is parsed correctly and sent to the intended recipient.



STATUS
Microsoft has confirmed this to be a problem in Microsoft Exchange Server versions 4.0 and 5.0. This problem was corrected in the latest Microsoft Exchange Server 4.0 and 5.0 U.S. Service Packs.
