I've had this email system for a while - I believe this is LiveMail 2011 - and in the past I have had my private and my business email accounts synced up and then a while ago my Hotmail account had problems and I uninstalled it and had to access it through a normal web page - not too long ago I synced it back up but was unable to send emails - I could receive them and view them - just unable to send them - I got bored yesterday and tried to fix that problem which then resulted in me uninstalling it and reinstalling .  Now this is the error message I get after five minutes of it trying to sync

Unable to send or receive messages for the Hotmail (xxxxxxx) account.
