unable to find free/busy information after changing primary smtp address
Hi, I have recently changed the primary smtp addresses of a few mailboxes from "name@domain.com" to "name@subdomain.domain.com".From then users of those changed mailboxes are unable to find free/busy information of users with smtp addresses having "@domain.com" suffix. They are able to find free/busy information of users with smtp addresses having "@subdomain.domain.com" suffix.Please help me out I have been working on this very hard but unable to find the problem.

Hi, Yes, all those users are in the same mail organization. OAB is published via virtual directories on CAS through IIS.

I'll suggest you to start the verbose logging in Outlook and check the logs after trying to do the F/B lookups Jonas Andersson | Microsoft Community Contributor Award 2011 | MCITP: EMA 2007/2010 | Blog: http://www.testlabs.se/blog | Follow me on twitter: jonand82

Well with the help of Microsoft support person we are able to solve this.Here is the resolution: autodiscover service fron outlook 2007 actually uses the primary smtp address to find the URL's of services like Availability service,OOF,OAB and unified messaging from client access server. For example if my primary SMTP is abcd@contoso.com then autodiscover will try to retrieve these URL's in the following ways: 1.first it will check if SCP objects are available on AD.if the system users are trying to access mails from is joined in the domain then it will work. 2.if SCP fails then it will check with two default URL's: https://contoso.com/autodiscover/autodiscover.xml https://autodiscover.contoso.com/autodiscover/autodiscover.xml 3.it will try HTTP redirect method. 4.it will use srv record lookup for autodiscover service. In our case clients are accessing from outside the domain so SCP method failed.it checked with default options in step 2 here's the problem. as we changed the users primary smtp addresses it is not able to communicate with autodiscover service on client access server.For example if we changed it "abcd@us.contoso.com" it checked for : https://us.contoso.com/autodiscover/autodiscover.xml https://autodiscover.us.contoso.com/autodiscover/autodiscover.xml which obviously failed because there is no DNS record for autodiscover.contoso.com pointing to client access server.Hence the solution will be: 1.create one Forward lookup Zone for the new smtp address suffix(us.contoso.com) and create a host record for autodiscover.us.contoso.com to point to client access server.But this will work only if SSL certificate used by client access server has this new domain in its subject alternate names field. 2.create a srv record on the dns servers local to users with the following configuration: Domain: new primary smtp suffix(us.contoso.com) service :_autodiscover protocol: tcp host offering this service:<<FQDN of client access server>> :-)
