You can increase both your avast! timeout: Internet Mail provider > Customize > Advanced (tab)
and your email account timeout (generally, right click the email account, choose properties and the Advanced tab of settings).
Thanks. Increased the timeout server to 4min (from 1min) on Outlook 2002 and I actually think it was a ISP provider issue due to I was getting kicked of via VNC every minute. I cycled the power on the cable modem & the router and now seems to be stable.
