The autodiscover work fine for computer in the domain, I change the URL of service to match the SSL installed on the Exchange 2007 Server to "mail.domain.com"
For computers not in the domain, they can open Outlook, send and receive email but they are not able to set their Out of office and access shared calendar.
I try the "Test E-mail AutoConfiguration" and the test failed because Outlook try to access "autodiscover.domain.com" and not the URL configured for the service.
I find a workaround : I add a CNAME in the internal DNS autodiscover.domain.com -> mail.domain.com
But now I get an error when I start Outlook because the SSL doesn't match name "autodiscover.mail.com"
If I click on Yes, it's work.
How can I get rid about this warning message ?
A wildcard certificate could be the solution but it's really very expensive.
Thanks for your help
