Hi All, I'm trying to get Activesync working on a Motorola Q phone. I managed to get our certificate installed on the phone, but ISA keeps rejecting the connection. Exchange 2003 SP2 Front End Server & ISA 2004 SP1 if that matters. The ISA logs show Client Username as anonymous and HTTP status code as: "12229 The server requires authorization to fulfill the request. Access to the Web server is denied. Contact the server administrator." I'm using the same listener as RPC over HTTP which uses Basic Authentication (SSL required). I have OWA using a different listener using FBA. OWA, OMA, and RPC/HTTP are all working OK. OMA works from the phone and Activesync works when cradled, just not over the air. . Can anyone think of something I might have misconfigured to cause this problem? Thanks, Jeff
