Please help me correct the autodiscover on my exchange 2007. The Autodiscover URL on my exchange server is https://email.domain.com/autodiscover/autodiscover.xml when I browse to this site using my web browser i get Service Unavailable - HTTP Error 503. The service is unavailable. The autodiscover SAN mentioned on my digicert certificate is autodiscover.domain.com when I browse to this site using my web browser i get Server Error 403 - Forbidden: Access is denied. You do not have permission to view this directory or page using the credentials that you supplied. I also noticed in IIS 7 under my exchange box, the MSExchangeAutodiscoverAppPool is stopped. I need to correct the autodiscover settings on my exchange 2007. please advise on how to correct this. Do I need to match the URLs on my Exchange & my certificate? Thank You Philip

Depending what names you have in your certificate, set the URI accordingly. Also, what is your common name? For e.g URL variousSukh

CN: email.domain.com SAN: email.domain.com autodiscover.domain.com The Internal URL for Autodiscover is https://email.domain.com/autodiscover/autodiscover.xml

Run Get-ClientAccessServer "CAS Servername" | fl *uri* and see what this is set to? If incorrect set correctly.Sukh

Hello, Please start MSExchangeAutodiscoverAppPool. And make sure that the URL can resolve internally and externally via DNS to the expected IP address of the CAS server. You can get more information on autodiscover and certificate from the article. Exchange 2007 Autodiscover Service Best Regards, Lisa
