I am running SBS2008 SP2 with exchange 2007 SP3. I had a corrupted IIS that I uninstalled and then reinstall. All SBS web applications are working within IIS except for Exchange. Emails are sent/received but the client access is not working properly. Symptoms: ActiveSynch to external smart phones is not working Outlook 2003/2007/2010 clients have update times in the hours and do not bring all message to the inbox OWA shows all incoming messages but cannot display them (error 500) I ran both SBS and Exchange Best Practices and found no problems When I run Remote Connectivity Analyzer, all test fails after getting through port 443 and resolve hostname in autodiscover It fails in all URL methods Test on SMTP is successful. I believed that there is a configuration connection that needs to be re-established between Exchange & IIS. What do I do next?John Lenz

I recommend that you post your question to the SBS forum becasue it installs Exchange somewhat differently than the standard product. http://social.technet.microsoft.com/Forums/en/smallbusinessserver/threads Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

THX, I did post there but no-one seems to know what is going on. I'll try again.John Lenz
