Cant retreive free/busy time - Outlook 2007 against Exchange 2007

Hi,

I am having problems with Free/busy time in Outlook 2007 working against a Exchange 2007 server.
The clients are external and member of the domain.
I use 1 Standard SLL certificate, and have set up a SRV record to get Autodiscover to work. This works fine. When i run the "Test E-mail configuration" from the outlook client. it says Succeded and looks fine, but when i try to add users to f.eks the Group Scedule it says "unable to retreive free/busy information"

Output from server:
