Starting sometime early this week I began being unable to send email from Outlook. I don’t believe the two are related, but I had installed Firefox around the same time and have since uninstalled it. We did quite a bit of testing to confirm my configurations were proper but all was good. As a last attempt I disabled the Internet Mail provider and I can now send emails from Outlook without problems.
My logs indicate that only virus file updates had occured since the new program release in April.
