I  can send emails but not receive any since Dec. 28th.  I downloaded windows 10, had windows 7, problem started before windows 10.  Have changed my password on my Microsoft acct, but that did not fix anything.  Should I get in touch with Windstream, I have had the same passcode with them for years. I have tried to set up a Outlook acct. but it can't seem to find me. Help, I have had this account for over 4 years, whats going on? I downloaded the Window Essentials 2012.
