If a user creates an autoforwarding rule that forwards e-mail messages from a mailbox to a custom recipient and that custom recipient is deleted, non-delivery reports (NDRs) are sent to the mailbox of the e-mail message originator and an event ID 290 that refers to the deleted address of the custom recipient is logged in the Windows NT Event Viewer application event log.


To verify that a user has an autoforwarding rule that uses a deleted custom recipient and fix that autoforwarding rule:

  1. From the mailbox of the user, send an e-mail message that is addressed to that same user. If the e-mail message arrives in the user's Inbox and an NDR similar to the following is sent to the same Inbox, proceed to the next step:

    The following recipient(s) could not be reached:

    Public, John Q. on 2/10/00 9:54 AM

    The recipient name is not recognized

    The MTS-ID of the original message is: c=US;a=XXXX


  2. In the application event log on the server that the user's mailbox is homed on, look for an event ID 290 similar to the following that was logged at the same time that the NDR appeared in the user's mailbox:

    Event Type: Warning
    Event Source: MSExchangeMTA
    Event Category: X.400 Service
    Event ID: 290

    A non-delivery report (reason code unable-to-transfer and diagnostic code unrecognised-OR-name) is being generated for message C=US;A=ADMINDOM;P=DOMAIN;L=MSG05INT-000128154450Z-35477. It was originally destined for DN:/o=DOMAIN/ou=INTL/cn=Recipients/cn=PUBLICJ§ (recipient number 1), and was to be redirected to . [MTA DISP:RESULT 18 136] (12)

  3. Use the address in the NDR to find the autoforwarding rule on the user's mailbox that is generating the NDRs by logging on to the user's mailbox and finding the address that is in the NDR attached to one of the autoforwarding rules.
  4. When you find the address, remove it from the autoforwarding rule, and then attempt to re-add the address from the global address list. If you cannot re-add the address, perform one of the following steps, as applicable:
    • Remove the autoforwarding rule from the mailbox.
    • Recreate the custom recipient and reassociate that address with the rule.
