SYMPTOMS
Users cannot reply to e-mail messages if the X.400 addresses of the recipients have a slash mark (/) as a field separator instead of a semicolon. The local message transfer agent (MTA) generates the following non-delivery report (NDR):

From: System Administrator

Sent: Wednesday, February 28, 2001 2:19 PM

To: c=US/a= /p=myorg/o=exchange/s=userZ/

Subject: Undeliverable: [X400:c=US/a= /p=myorg/o=exchange/s=userZ]

Your message did not reach some or all of the intended recipients.

Subject: [X400:c=US/a= /p=myorg/o=exchange/s=userZ]

Sent: 2/28/2001 2:01 PM

The following recipient(s) could not be reached:

c=US/a= /p=myorg/o=exchange/s=userZ/ on 2/28/2001 2:18 PM

The e-mail address could not be found. Perhaps the recipient moved to a different e-mail organization, or there was a mistake in the address. Check the address and try again.



CAUSE
This issue can occur because a slash mark as separator in an X.400 address is possible in Exchange Server 5.5, but is not handled correctly in Exchange 2000.
