Sounds like your PC is using a POP3 account, instead of IMAP. So what's the model number for the Samsung product you're having problems with?
I have a problem with Hotmail.
I have my Hotmail account set up in the email app from Samsung, and it works well.
But when using Hotmail on my PC, it says that I have unread mail, even though I have already read them on my phone.
Does anybody know a solution to this?
Thanks in advance!
