WLM 2012 suddenly quit receiving E-mails with Windows 10. I know WLM works cause I can send from my computer to my phone, but nothing shows in sent messages.

This morning my WLM 2012 quit receiving E-mails on my computer, I recently downloaded Windows 10 a month ago. I know I can send out E-mails because they appear on my phone. But nothing shows in the sent folder. I'm still receiving WLM e-mails on my phone but they don't come up on my computer when I hit the send/receive button. A note at the bottom says no new E-mails.
