Why is my mail notification showing new/unopened mail but its not true?

Mail Notification showing new/unopened mail but not true

My work e-mail sends and receives just fine. The problem is on the home screen mail icon. It shows I have new/unread emails when I have opened and read all of them. It keeps increasing and it shows 20! I deleted unopened and that didn't fix it. Any ideas?

Re: Mail Notification showing new/unopened mail but not true

Are you using any launcher in particular? It might be that. I've had issues with Nova's counters and also with Themer. If I switch to the stock launcher (TouchWiz, in my case), the counter shows up fine.
