Outlook clients cannot connect to Exchange 2007 server, OWA works fine.

Background:
I have 1. 2008 DC and 2 2K3 DC's, 1 Exchange server 2003 which still workes fine,
1 Exchange server 2007.
When moving mailbox or creating a new mailbox in E2K7, OWA workes fine, but only getting "Server Available" when trying to connect with Outlook. Tested both Outlook 2k3 and 2k7.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

What kind of certificate are you using? Self signed, bought (which), is it a certificate with multiple hostnames in it (UUC).

Instructions for creating a self signed certificate with multiple hostnames, you can find here: http://technet.microsoft.com/en-us/library/aa995942.aspx

Also, could you check if you  press and hold ctrl and then click the Outlook icon on the taskbar on Outlook 2007 client. What problems do you see there?

I'm using official certificate for the public mail domain.
That certificate is installed on the ISA server, so I dont have any internally.
Should I create an internal CA and issue a certificate for the private (.local) domain?

You can find a lot of info from Sembee here: http://www.sembee.co.uk/default.aspx .

A guide for isa server, you can find here (I have no isa server, so I have NOT tested this!): http://www.isaserver.org/tutorials/Generating-SSL-Certificates-Exchange-2007-ISA-Server-2006.html

In general the UCC certificate should contain the following alternate names: autodiscover.domain.com ; domain.local ; NETBIOS name and as common name the external fqdn (webmail.domain.com).

I hope you can get further now.
