I have Yahoo mail, gmail, and verizon account. The Yahoo and Gmail work perfectly. The issue is my verizon account. I will read or reply to a message from my phone and it doesn't show that when I log-in on my laptop and vice-versa. So I end up replying twice to same message because I can't remember what I have replied to. I spoke to Verizon tech today and they told me it was a samsung issue. I spoke to samsung and they said since the other email accounts are working it is an issue with verizon's email service. Please help me out. Thanks.
