I don't use yahoo, but I have had this issue in the past with Gmail. It was due to using two factor authentication, so if you have that (not sure if yahoo does) I recommend disabling it for at least now. There may be a better solution but I don't have one.

This happens frequently on my PlayBook, has happened once on my Z10, and never happened on my earlier BBOS BlackBerry models that were of course on BIS. I don't know the exact problem, but I see it (at least in my case) as a hiccup of sorts between the email client on the devices and the Yahoo system. It never happens with Windows Live, not even on the PlayBook.
I don't know what can be done.
