I am helping a friend who has recently updated her Win 10 laptop and did the Win 10 upgrade to her Win 8.1 Surface Pro. She now finds that when using the "Mail" tile for email neither her Yahoo or gmail account provides the usual auto fill choices from her contact list for completing the name of the person for whom the email is intended. That function occurs just fine when accessing the accounts from Edge, but not from the Windows Mail tile. What have I missed in doing this setup? I use an identical HP laptop and have no such problem. Settings seem to be the same on both laptops. Suggestions appreciated.
