Our Outlook Clients are getting quite a few of the error message below in the last couple of days. When we open the Undelivered report, there is a "Send Again" button that seems to know that there was a problem that can be corrected. If we "Send Again" the message appears to get delivered successfully. We are using Exch 5.5 and I don't see any error messages on the server yet.
Does anyone know what I can check on the server to get to the source of this issue?
Thanks if you can help. I'm still searching for the answer.
