Thanks for the answer about the time, Eric, I figured it was GMT (however, they should've left it with US time, as I'm sure very few Americans know how many hours difference there is with us and GMT)...
Anyway, I'm leery about deleting the account, as it will delete all the emails. And backing them up didn't do me much good when I updated my OS a while back. When I called support, they told me my back up folder didn't actually have the emails on my computer, so I couldn't just load them back in. It was a Twilight Zone moment for sure, as I could see the folder, and it was a large one, so they were in there, but she said no. I forgot at this point how I actually was able to retrieve them.
How would it work if I deleted it, and then recreated it? Why is there no other option to have it work? And why would it work fine for incoming and not outgoing? Does it matter that when I click on "Advanced" in the Accounts window, that it shows the account name, but for "path prefix" it's blank?
