Outlook 2010 has worked fine for my old Prodigy.net address for the last 10 years. MS stopped supporting Outlook 2010, forcing me to subscribe to MS365 and its version of Outlook. It does not log on using my prodigy.net address. I had to set up a gmail.com account. How can I get Outlook in MS365 to access my prodigy.net account? I have hundreds of contacts that know me as prodigy.net, and none that know me as gmail. I am paying for something I can't use and am not happy about it.
