Availablity Service on Exchange 2007
Hi all,
some users would like to use the availability service (free/busy) when schedule a meeting, but right now, users cannot gather the information when inviting attendees. An error "No information. No free/busy information could be retrieved." occurs after a
period of time.
Below is my configuration (not sure it's enough or not):
[PS] C:\Documents and Settings\Administrator>Get-ClientAccessServer |Select Name, *internal* |fl
Name : CAS1
AutoDiscoverServiceInternalUri : https://cas1.local/Autodiscover/Autodiscover.xml
Name : CAS2
AutoDiscoverServiceInternalUri : https://cas2.local/Autodiscover/Autodiscover.xml
[PS] C:\Documents and Settings\Administrator>Get-WebServicesVirtualDirectory |Select Name, *URL* |fl
Name : EWS (Default Web Site)
InternalNLBBypassUrl : https://cas1.local/ews/exchange.asmx
InternalUrl : https://cas1.local/EWS/Exchange.asmx
ExternalUrl :
Name : EWS (Default Web Site)
InternalNLBBypassUrl : https://cas2.local/ews/exchange.asmx
InternalUrl : https://cas2.local/EWS/Exchange.asmx
ExternalUrl :
Due to our infrastructure setting, all of us cannot connect (ping) to cas1.local or cas2.local, but we can connect to it's external url
https://mail.company.com/, so we're using RPC over HTTPS to connect CAS via Outlook. But I found some interesting thing, when I tried to configure the host file to resolve the
internal IP address (192.168.1.xxx), and make my laptop able to connect to the one of the CAS server directly, I can retrive the free/busy information of the attendees, but I will get a certificate error as the name on the security
certificate is invalid or does not match the name of the site. Can anyone help? Thank you!
One more question, how Outlook to decide to use Internal URL or External URL?
Thank you very much !!

But after I added the above record into my host file, I can get the below result from "Test E-mail AutoConfiguration".

Hello,
To get the free/busy feature work for Outlook Anywhere clients, you need to verify the following check points:
1. Public records for “autodiscover.company.com” and “mail.company.com” so that the external clients can successfully resolve
the autodiscover and availability service.
2. The external url for the availability service is set to “mail.company.com”.
3. A valid certificate for ”autodiscover.company.com” and “mail.company.com” name spaces and enable the certificate for IIS.
Thanks,
Simon

You are testing exrca for ActiveSync, well moreover what I see from that report is your port 443 is blocked on the firewall, incase if you Outlook Anyewhere to work we need 443 open on the firewall as well..Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.
