Email Proxy error

This issue has been solved. See solution.

We are using Symantec Endpoint 11.0.6005.562 and Outlook 2007. On only one of our computers (all of which are connected to a Microsoft Exchange server) we get intermittent Symantec Email Proxy error 1003.9 that says, "was unable to be sent because the connection to your email server was interrupted. Please open your email client and re-send the message from the Sent Messages folder." There have been no attachments to the outgoing messages. I have tried to increase the server timeout and continue to get these messages two or three times a day.

It is possible your system is infected. Spam is often sent from botnets of compromised computers. If large numbers of the errors listed above are appearing I suggest you treat this as an infection.
