I am running Windows 10.  I have been using Windows Live Mail, but want to convert to Outlook 2016.  I would like to know what I need to know and what I need to do before taking the final step and start punching buttons.  I have been trying to read up on this, and there are a lot of things that I don't understand.  Do I need an EML to PST converter?  Which one is best?  

The bottom line is......................I need help!!!
