Exchange Server 2003. Messages were successfully delivered over a month ago, but received NDR messages last evening? PLEASE LOOK
OK. So here is the deal. Running Exchange Server 2003. on Server 2003 StandardR2. Came in this morning and 3 people (possibly more though) reported that they had received massive amounts of NDR's. One user had 44. They were all messages that were successfully sent over the course of the previous month and a half and as recent as 6 days ago. Take for example this one email. It was sent 6/15/2009 at 10:00 AM, and according to message tracking, it was successfully sent. The NDR came last night: From: System Administrator Sent: Tuesday, July 28, 2009 8:19 PMTo: SENDERSubject: ########### Your message did not reach some or all of the intended recipients. Subject: RE: ################## Sent: 6/15/2009 10:00 AM The following recipient(s) cannot be reached: ****@****.com on 7/28/2009 8:18 PM Could not deliver the message in the time limit specified. Please retry or contact your administrator. See this image:http://i662.photobucket.com/albums/uu349/cookdorf/screen-capture.png - There are 3 recipients I do not understand this at all. It successfully sends to all three recipients, then decides to resend itself to one of them, and then again, and then again, and then sends an NDR? This is the same story on multiple emails all with an NDR occurring within one minute of this one. 7/28/2009 at 8:18 PM. Please help! Thanks, Cookdorf

Hi,Its looking more time out issue when sender is not able to deliver mail in specified time limits.pLease check some below points to trouble shoot this issue.1: Try to send message thru SMTP command to recepinets and see error/NDR code.2: Do you get NDR code 4.4.73: Check with other sender to send mail those recepinets4: Check whether your server autheticate revrs lookup as some of receive server do reverse lookup for receiv mail and sender should have vallid PTR records.Please update me status.

Anil Your response doesn't really pertain to the specific issue at hand. The email in question successfully sent on 6/15/2009, but for some reason the server decided to resend the message. After the third resend of the message, it creates an NDR. The user is not resending the message, as it would be a different message id. And it has been confirmed by the recipient, that they have received multiple copies of the same email. (check out the picture I linked to) All the NDR's were sent at the exact same time (over 100 NDR's sent last night at 8:18 PM).. Thanks for the response though.

This could be related to a corrupt message in the mailbox, Or a PST file corruption. Have you tried moving the mailboxes to another store. If the move fails try to export the mailbox using exmerge if it still fails try using MBDVU32 to delete the corrupt message. http://tinyurl.com/q7z6j

Hi Cookdorf, I suggest you refer to following thread: http://social.technet.microsoft.com/Forums/en-US/exchangesvradmin/thread/81505df9-6e2a-425d-892b-088f30d1195a I would like to explain the issue may occur if the messages cannot be removed from SMTP mailbox after message is delivered (The issue may occur if Anti-virus software was scanning the messages and locked them). Then, when the SMTP service is restarted, SMTP service picked up the messages and attempt to deliver the messages again.
