Outlook Issue

I keep getting the following message when I send larger attachments, 2 meg or more:

A time-out occurred while communicating with the server. Subject ‘Mail’, Account: ‘mail.comcast.net’, Server: ‘127.0.0.1’, Protocol: SMTP, Port: 25, Secure(SSL): No, Error Number: 0x800CCC19

This started when I loaded AVAST

I think it has to do with the timeout limit set in Avast. Mine is set for 120 seconds so if you have large file that takes longer than that you will get a timeout message. Try increasing the timeout setting in the outlook provider.
