Hey Guys, most excellent work around. Works a charm. As a software engineer (and I'm guessing here too) that Norton doesn't have a hook into Outlook's control of the dialup connection. Therefore Outlook is handing everything off to the Norton proxy, getting the all okay (from the proxy), believes it's sent the mail and hangs up. Meanwhile the Norton proxy, still processing, gets the valid connection dropped and throws the mail away. It's all bad really, Outlook thinks it has sent the mail, but Norton know's it got *null* and has been a bad boy. In my opinion, Norton should be able to fix this, if this is the case, by simply handling the mail server repsonse, and *pretending* to Outlook that it's still being sent.... Still, Chris, you're on the money with the solution. Though I found you DON'T need to turn off the progress indicators, as they no longer come up. In fact I'm going to leave them on so that if Symantec fix this behind my back and "patch" my config I'll know as the progress feedback will rear it's ugly head. So to recap; Turn OFF, NIS Privacy Control Turn OFF, Norton Antivirus > Scan outgoing mail Turn OFF, Norton Antispam > Learn by reading my outgoing mail I tried various combinations of these too. NIS Privacy NAV Scan Out AntiSpam Learn N Y Y N N Y Y N N Y N Y N Y N None of these combos worked. I'd say our friends at Symantec need to "beef" up their process engine. Probably written by a grad.
