We are having an issue where our emails are not being marked as read anywhere other than on the email client itself.

When viewing the email on computer A you get all the email, and you see any messages you have read as read. When you view the email on computer B you get all the email, and you see all the messages as UNread. When you view the email via webmail you see all the messages as UNread.

If the PC Email client can send a message to the server flagging messages for deletion, why can't it send a message to the server flagging messages as read on the server.

Even if I weren't using multiple computers this would be a problem, for example if you ever had to replace the computer, every message you have would show up as new-UNread.

I am fairly sure, I had, in the past, email with pop that did mark the messages as read on the server.

I do not want any comments recommending IMAP at this time.

The Email we are using is POP, the client we are using is Windows Live Mail 2012, on a mix of windows 8 & 7.

We are using SSL both incoming and outgoing.
