We have a programmer who has written an application to send emails to users in a DB. Sometimes the program works and other times it doesn't. All emails are addressed to persons on the same domain/exchange server as the person running the application. When the application is run, the Outlook 2007 warning message appears, the person OKs the warning message, the email message goes to the OutBox and is sent, and then several minutes later a message from System Administrator will show in the InBox stating:
Your message did not reach some or all of the intended recipients.
Subject: Rejected Timecard 0046004042 OLSJAM
Sent: 7/2/2010 9:54 AM
The following recipient(s) cannot be reached:
Notice that it doesn't state a recipient in the message.
I can go to SentItems, select the message to resend, and it will go just fine.
Any ideas? I'm not sure if this is an Exchange, Outlook, CDO, or MAPI issue.
