Help Please. Outlook wants to re-download duplicates of 10,000 existing HOTMAIL emails on the server I want to keep. 

I have let it go before and do the re-download and then deleted the duplicates when finished. However, several days later, it wants to restart again and its sucking up valuable band width and taking up resources.

Outlook is set up as:
Incoming as: pop3.live.com (995)
Outgoing as smtp.live.com (587)

Its really annoying and killing my Outlook experience. 

Please help with how to stop this.

When I try to re-download it says incorrect password. I double check and the password is correct. I can sign in with this information on my Xbox live app on my phone and in the computer, but the Xbox itself.
