I can no longer get into my Microsoft Exchange account. I constantly get a message that says "Unfortunately, email has stopped". It has not synced for over 10 days. I have tried restarting the phone, uninstalling updates to Android System WebView, and tried to remove the account. When I try to remove the account it gives me the same message. Because it is a factory installed app, I cannot delete and reinstall. Any suggestions? It is pretty important that I'm able to access my work email away from my desk.
