I get System.Net.WebException: The request failed with HTTP status 401: Unauthorized. when I try to set up a new user in exchange 2010

Our exchange 2010 is set to “force” the automatic propagation of settings into the user profile, including the checkbox for “Connect to Microsoft Exchange using HTTP” and filling the information for the HTTP proxy and authentication methods.  I ran this yesterday to stop that

Get-outlookprovider –identity EXPR | remove-outlookprovider

Then I recycled the app pool in iis

Now when I add a user I get this

Warning:
The cmdlet extension agent with the index 0 has thrown an exception in OnComplete(). The exception is: System.Net.WebException: The request failed with HTTP status 401: Unauthorized.

Any help would be appreciated.
