Your response is a little confusing.
What is the "it" that did not work on 3 computers that you have avast installed on?
A number of those I support (as I do also) have Windows Live Mail installed with a mix of Hotmail, IMAP and POP accounts active along with avast running without any problems whatsoever. If Windows Live Mail did not work with avast you would see large numbers of error reports in this forum - they are not here.
However, none of those I support have the Outlook Connector installed.
You did offer to help - that's why I suggested uninstalling the Outlook Connector.
Perhaps you would consider trying to run with avast installed but with the Webshield turned off - that, at least, would help a little.
You should read carefully.
I had Outlook Connector. Uninstalled because it didn't work (on 3 computers with Avast).
Installed Windows Live Mail on the same 3 computers - didn't work.
Sent the Log from laptop (Windows Live Mail), got the answer it's my AV which makes the problems.
Uninstalled AVAST from my laptop, Windows Live Mail worked. Uninstalled it, Installed Outlook Connector - Worked.
The 2 other computers aren't available to me at the moment, I will try them as well later this week.
