Auto-complete for email addresses stops working very frequently.  I have tried all the recommendations provided for other questions on this subject, and none of them work, or work only sporadically.  I am using IE 10.0.9.  I have tried optimizing the browser, clearing browsing history, reviewing AutoComplete settings in Internet Options Content, and reviewing the recommended settings in Internet Options Advanced.  I have closed IE and reopened, even rebooted.  None of this works!

This is becoming so frustrating that I might need to change browsers.  Since IE and Outlook are both products of Microsoft, I would hate to think I have to switch to a non-MS browser to fix this problem.

PLEASE HELP!
