Moved to a new post....

Hi Diane,

I realise these posts are 3 years old but I'm having the same problem with my Outlook 2011 for Mac: my server seems to download all the emails from certain accounts (I have only been paying attention to my work email account)-I have 11,200 in that folder whereas I should probably have half that amount of mail. I've tried to delete the duplicates but they seem to download again. 

Q: when they are deleted from the Server (web based mail)...do I then have to delete them from the "Deleted" items to prevent them from downloading again? I didn't think I have to.

What could be the explanation for why my emails keep downloading-someone mentioned to me "flagging" and that my server is not flagging read messages properly? 

My Server is BT/Yahoo Mail (UK)....

Any guidance would be appreciated...

BW...
