Exchange 2007 - Mails Not Being Sent


I wondered if somebody could offer some help.

We have a 3rd Party System that connects to our Exchange Server to send emails.

Yesterday as usual it was working send 400 odd emails, but 4 never got sent, but the 3rd Party says they sent them to our Exchange.

Is there a log on the Exchange Server somewhere then says if there was a connection issue?

I had a similar problem. Can you please verify if the "Microsoft Exchange Mail Submission" service is running. If not start it.

Also verify that all exchange services are running. (The one which should run 'automatically)

Check Queue Viewer in the EMC to see if any is stuck or maybe check the usual event viewer (Administrative Tools) on the exchange server to see server interupts.

That is running fine, the 4 missing were in the middle of a batch and the rest went and these ones didn't.

Madjax - Nothing in the queue or the event viewer either.

I didn't know if there was a log that says "Attempted Connection" or similar.

Aha, Log into EMC and goto Message Tracker. See if you can track those message using this tool. You should be able to see the messages, if those 4 are also in the list they were sent, if not then they probably were never sent by the 3rd party.

No they are not in the list.
Hi essexboy80,
   Then it should be confirmed. If you see the other messages and not these 4, then they never reached the server.

Hope you can ask the 3rd party to resend it.
