Unfortunately Email Has Stopped

[mrslynch]

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.

Also, when I try to use my gmail account to compose a message, this error message comes up constantly.

Use the Microsoft Outlook app.
