I am using outlook 2013 on my home computer. I purchased it through a home-use program from my employer. I have my personal email set up (outlook.com) through the "Hotmail connector". Lately, I've been receiving duplicate emails - emails that are already in my inbox on my computer are being downloaded again when I sign in to outlook. I'm thinking it might be a sync error, but I am not sure. I have the mobile version of outlook.com installed on my cell phone and tablet
