Anyone got the powershell command to set autodiscover to NOT check the box "Only connect to proxy servers that have this principal name in their certificate" ? I know how to edit the name in the SCP, but can't seem to find where/how to remove the setting entirely.

Please check this post at my blog, maybe it helps: http://www.sch0.org/index.php/2008/04/15/exchange-2007-autodiscover-issue
