Hi,I have existing autodiscover site but unfortunately someone missed out the subject when creating generating the certificate on the autodiscover.domain.com . It was only mail.domain.com that was on the certificate.That is why we got the error when doing the https://autodiscover.domain.com/autodiscover/autodiscover.xml<?xml version="1.0" encoding="utf-8" ?> - <Autodiscover xmlns="http://schemas.microsoft.com/exchange/autodiscover/responseschema/2006"> - <Response> - <Error Time="05:45:41.8288382" Id="3067181984"> <ErrorCode>600</ErrorCode> <Message>Invalid Request</Message> Can I just put autodiscover.domain.com in the current certificate or just to hack? Sorry! This is the fastest solution.I am planning to get another certificate ready but unfortunately I dont want to mess the current production site which uses the old certificate on Outlook Anywhere and OWA.Can I have 2 website in the Exchange CAS co exist in the current box and installed the correct one certificate and not having to mess the production? Can you give some insight on this. Appreciate it.The Current Outlook Anywhere, OAB and OWA works fine with Outlook 2003, Outlook 2007 but Out of office and Availability Service (Calendar & Schedule Asst) is missing and "the server is not available..." on Outlook 2007. When i troubleshoot the IIS logs, it was 4xx but i believe it was cerficate that messing the connection drops on the Out of Office.Thanks for the help.~ Jodan

yes, you are correct. Its the cert missing on the OOF messages. why dont you try a wild card certificate (*.domain.com). This will handle all the request either autodiscover.domain.com or mail.domain.comRaj

I have existing Autodiscover site but unfortunately someone missed out the subject when creating generating the certificate on the autodiscover.domain.com . It was only mail.domain.com that was on the certificate. Use DNS Service Location (SRV) records to locate the Exchange Autodiscover servicehttp://support.microsoft.com/kb/940881. You must remove the A or CNAME record for autodiscover.domain.comfrom your external DNS, since this lookup will be preformed before the SRV lookup.This will work with your existing certificate. Availability is depended on Autodiscover. The downside: Windows Mobile 5.xto 6.5 don't handle SRV lookups. Neither does the iPhone, but Entourage 2008 WES and OS X Snow Leopard Mail does :-)Test it: Exchange Remote connectivity Analyzerhttps://www.testexchangeconnectivity.com/And from OutlookConfiguring Outlook 2007 with Exchange Server 2007http://www.msexchange.org/articles_tutorials/exchange-server-2007/management-administration/configuring-outlook-2007-exchange-server-2007.htmlAnd you're done.

Actually I have tried that. Did not work.https://autodiscover.domain.com/autodiscover/autodiscover.xml<?xml version="1.0" encoding="utf-8" ?> - <Autodiscover xmlns="http://schemas.microsoft.com/exchange/autodiscover/responseschema/2006"> - <Response> - <Error Time="05:45:41.8288382" Id="3067181984"> <ErrorCode>600</ErrorCode> <Message>Invalid Request</Message> Still the same issue and Out of office and Availability Service (Calendar & Schedule Asst) is missing and "the server is not available..." on Outlook 2007. It is the certificate. I have to recreate the certificate. Thanks for the help.

The conclusion that "it is the certificate," based on the information you have provided, is not correct. https://autodiscover.domain.com/autodiscover/autodiscover.xmlwill not work with DNS SRV. And my proposal does work.With your certificate, this should bethe URL for auto-configuration:https://mail.domain.com/Autodiscover/Autodiscover.xml That is the way Autodiscover is configured at my job and here at home with SBS 2008. If you don't get this to work, you must have configured your DNS SRV record wrong. In order to verify the setup, do a nslookup (edited):C:\>nslookup > set type=all> _autodiscover._tcp.domain.com Non-authoritative answer:_autodiscover._tcp.domain.com SRV service location: priority = 0 weight = 0 port = 443 svr hostname = mail.domain.comThe Microsoft Exchange Remote Connectivity Analyzer would display these stepshttps://www.testexchangeconnectivity.com/(1) Attempting to test potential AutoDiscover URL https://domain.com/AutoDiscover/AutoDiscover.xml Failed testing this potential AutoDiscover URL (2) Attempting to test potential AutoDiscover URL https://autodiscover.domain.com/AutoDiscover/AutoDiscover.xml Failed testing this potential AutoDiscover URL (3) Attempting to contact the AutoDiscover service using the HTTP redirect method.
