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.
