We have an exchange 2007 server behind 2 ISA 2006 firewalls in a front-back configuration. We have OWA up and running, we're currently working on Active Sync. When trying to use the Microsoft Exchange Remote Connectivity Analyzer we're getting the following result: An HTTP 403 was received because ISA denied the specified URL When I monitor our ISA firewalls I'm getting the following logs: Front firewall: 12202 The ISA Server denied the specified Uniform Resource Locator (URL). Back firewall: 12239 The server requires authorization to fulfill the request. Access to the Web server is denied. Contact the server administrator. I've checked certificates, permissions and my firewall rules and still have not come up with an answer. If anyone has any thoughts I'm definitely open to ideas. Thanks in advance.

Hi,The error message does indicate that the ISA server is not configured properly to publish active-sync.This might help:http://www.isaserver.org/tutorials/Publish-Microsoft-Exchange-Active-Sync-EAS-ISA-Server-2006-Part1.htmlLeif
