When Avast! is disabled completely through Stop On Access Protection I can send email. When all providers are stopped I cannot. I get varying lengths of error message, all apparently the same cause. The longest says "The connection to the server was interrupted. ... The server responded: 421 Cannot connect to SMTP server ... connect error 10061"
All was fine with Outlook 2003. I installed Office 2007 Enterprise and allowed it to upgrade my Outlook 2003 email.
I have checked the Services (2 auto, 2 manual). I have checked Outlook Trust Center. I have increased Outlook timeout to 2 min but the error comes back in say within 10 secs.
I am curious as to why there is a difference between stopping OAP (can send) and terminating all providers (can't send).
I can send from TheBat! without a problem.
Windows XP Pro SP2, Avast! 4.7.1029
