Ive added all of my e-mail accounts and all work fine by them selves but when i use the stock e-mail app i get.....Check login information or try about 15 min later because your account could be blocked due to frequent login attempts. When i go to settings and re-type my passwords (which all work) it deletes one of my connected e-mails, which happens to be my primary e-mail. Anyone have a explanation and/or solution?
