@DavidJ7,
I have the same error message. Both of my email accounts (yahoo and windows live) will load my inbox with messages, but when I tap to view a email message, I get error pop-up, "The application Email (process com.android.email) has stopped unexpectedly. Try again." If the accounts weren't configured correctly, my inbox wouldn't load all the new messages. I'm stumped. I've deleted the accounts and readded them. Same problem. Need help.
