Mail was working fine then all of a sudden, after I deleted a few seemingly unrelated apps, it deleted my Yahoo account that was linked to the mail inbox. I have tried every possible combination from changing ports to changing SSL to TSL plus IMAP, POP....etc...keeps saying my username/password is incorrect. However, I can log into Yahoo using the yahoo mail app with the same username/password that it says is incorrect. I don't like the Yahoo app and would like to get my mail account linked back the way it used to be. Any assistance would be great!
