If you're using Windows Live 2012 for e-mail
 

My personal e-mail is a Windows "live" account. I've had it for year, it being the successor to "Hotmail". To keep my personal e-mail accounts separate from my work accounts, I use Windows Live Mail 2012 for personal and regular Outlook 365 for work.

Appearently, Microsoft is updating the e-mail service and Windows Live 2012 e-mail program no longers works with the new "Outlook.com" e-mail. If you get error 3219, you are having this problem.

There is a solution: IMAP

You can use IMAP services in Windows Live Mail and in Outlook.com
