Bought new phones and salesperson set up our accounts they work on the phones but not my home computer, windos email, or my husbands kindle email. talked with Verizon, google and they say its windows 3rd party e-mail that's not working, went in to get it set up but just won't work. Server does not recognize name and password

So it won't let me in, can anyone help me with this dilemma???

thank you for your time
