I just updated my Toshiba laptop to Windows 10. When I use the new Intenet browser, Windows Edge, to call up the Verizon email client at Veerizon.net the area where the "Compose" button and mail boxes, on the left side is blank The list of received emails is there and is okay.. When I use the "open with Internet Explorer" option in the browser I get a nearly blank page. This makes it impossible to send and receive at Verizon.net.
I also have several iMacs and no problems with Verizon.net with them.
