XFOR: Dirsync Error: Warning [30] Message Contains Duplicate Email Address (187779)
The information in this article applies to:
- Microsoft Exchange Server 4.0
- Microsoft Exchange Server 5.0
- Microsoft Exchange Server 5.5
This article was previously published under Q187779 SYMPTOMS
After a new Exchange Server computer has been added to an Exchange Server
site, that is a requestor in directory synchronization (dirsync) with a
Microsoft Mail 3.x postoffice (PO), the following warnings may appear in
the Dirsync log:
Warning [154]Non delivery report
Warning [30] 154 Message contains duplicate email address. Mail item
was not delivered to(requestor name)
Address lists updates will not be propagated to the Exchange Server site,
and no errors or warnings will show up in the Event Log for the Exchange
requestor.
CAUSE
The new Exchange Server computer has been given the Microsoft Mail address
"SHADOWNET\SHADOWPO\SYSTEM1" under the Directory Synchronization tab as the
Requestor server. Consequently, the errors occur and dirsync stops
functioning.
Usually, when a new server is added to the site, directory replication
checks for other MS Mail connectors and if it finds any, it automatically
increments the MS Mail address in sequential order. For example, if a
fourth Exchange Server computer is added to a site with an MS Mail
connector, as a dirsync requestor, it will look for the connector during
directory replication, and then assign it the address
SHADOWNET\SHADOWPO\SYSTEM4.
WORKAROUND
On the Directory Synchronization Properties page, highlight the new server
and edit the Microsoft Mail e-mail address.
