Outlook problems in sending email

The only way I seem to be able to send mail from outlook is to disable the email scanner, ?, otherwise it just sits there reporting the below error message, any ideas

Task Sending’ reported error (0x800CCC0F) : 'The connection to the server was interrupted. If this problem continues, contact your server administrator or Internet service provider (ISP). The server responded: 354 go ahead ’

I have noticed that issue as well. It appears to have started after the last Microsoft Patch Tuesday. I noticed that Outlook was slower to load and to do a send/receive after loading Comodo last month, but this new issue is too much. I have disabled the email scanner, rebooted, and now Outlook 2007 works great again.
