I have an AOL account and two Verizon.net accounts that I must keep. They are the contact and ID for many other accounts. I was able to set up the accounts in Win 10 Mail so that they send and receive mail. However I have been unable to import the e-mail addresses. I am unable to understand neither the convoluted instructions nor the nomenclature used by the helpless desk.  I have transitioned through every iteration of Windows from DOS to 8 and the early 10, the latter two on my laptops sans mail.

Please let there be someone out there that can explain the process in plain english and is willing to do it for me.

Thank you
