Outlook says it’s constantly downloading emails but nothing comes in

Hello 

I updated my Mac yesterday to the newest Yosemite 10.10.2, and since then my Outlook has been giving me issues. 

I have 2 accounts linked to my Outlook, one being a work (POP) account, the other is my Hotmail account (IMAP)

It started off by downloading duplicates of all my emails I've received since the update over and over again.  

As well as my junk mail box having 39 emails in it and overtime i deleted them they came back. 

I checked the "prevent nap app" option in outlook's info following advice from another forum. This seemed to fix the junk mail problem and the duplicates being downloaded. 

But now it constantly says "Inbox : Downloading (Status bar) 1/81" in the bottom right hand corner - which i know means its bringing emails in. It completes the download of all 81, but nothing shows up in my inbox. Then it starts all over and says its downloading 81 again. Over and over. 

I can receive and send all new emails from both accounts without and issue, it just says its downloading these 81 emails which never arrive? And due to it constantly downloading these "imaginary" mails, its slowing my computer down terribly driving me insane. 

Please someone help!
