I finally tracked it down to the Outlook/Exchange feature in Avast. (Once I turned it off, our email zoomed out of here!) After our email was sent, I went back into avast to turn the Outlook provider back on. When I did, I got the provider is waiting for a subsytem error that so many else have received. I went in and removed the Avast plug in from the Disabled Items list in Outlook.
Now, I’m getting this error (Task ‘latd.com - Sending’ reported error (0x80042109) : ‘Outlook is unable to connect to your outgoing (SMTP) e-mail server. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).’). This is the first time I’ve gotten this error and I got it right after removing the plug in from the Disabled Items list. ???
It seems to be working fine for now knocks wood. I thought Outlook/Exchange was supposed to protect my Outlook email… why is Internet Mail scanning it? Do I even need to have O/E turned on?
That is the question, indeed… why was Internet Mail picking it up if the Outlook/Exchange provider was running.
This is not the way it usually works (the Outlook/Exchange shield normally disables Internet Mail in the context of the Outlook process).
