Using a Yahoo-based e-mail that I linked up to the Evo. The e-mail on my phone doesn't update at all with what I do on the computer with the e-mail. So I can read and/or delete the e-mail on my computer and it still keeps it as in my inbox and unread on the phone. Thus, the phone can say I show 200 unread emails even though I've read them all. Is there a way to fix this or change the settings?
