When I send an email from Outlook, I notice that in the SENT folder the email is showing twice on almost every email I send. This is rapidly filling out my SENT mail folder.

How can I resolve this issue?

Does this help? http://lmgtfy.com/?q=why+does+outlook+show+duplicates+in+sent+folder

I am not sure I quite follow. Are you suggesting this is NOT an AVAST issue but simply an Outlook issue?

I stand corrected somewhat. Perhaps it was an Outlook error after all (I am using it for Hotmail).

This corrected the issue.

Have no idea so i googled it, and there was lots of none related avast hits

Good if you solved it :wink:
