The issue that has cropped up for me in the past few days has been my email(which is not a web based email) says that my settings have changed. I click on that message. It takes me to the settings menu. I don't change anything, just click save and then it works fine. I go back to the message app and do a manual sync and it gets my messages. Weird, huh?
I'm constantly getting this message for my pop3 email. I clear the error, recheck emails, and it works fine. Until i get the error again a few hours later. Every morning, it's sitting there with the error. Really annoying.
