If you use an HTTPS (Secure Sockets Layer, or SSL) connection to a Microsoft Outlook Web Access (OWA) server through an HTTP proxy, the Internet Explorer lock icon appears briefly and then disappears. If you refresh the page, the icon reappears briefly but disappears again quickly.


This behavior occurs if the OWA server is configured to use Negotiate or NTLM authentication.


To work around this problem, use Basic authentication to authenticate with the OWA server. This workaround is safe because Basic authentication is performed through the SSL connection.


Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.


The connection is secure, but the lock icon is not displayed correctly.
