I installed a new server 2008 R2 with Exchange 2010. I have a valid SSL certificate on gateway.company.com and i cannot connect with external outlook clients.

What is wrong? And do i need to enable Outlook Anywhere to use this? How can I enable this?

If you have allowed autodiscover to configure the setting, then Outlook will only connect on TCP/IP if it can. That is by design. HTTPS is the failover.
Is the server exposed to the internet? If so then you can test it with the Microsoft test site. https://testexchangeconnectivity.com/

This feature either works, or it doesn't. No middle ground.

Well, thanks.
@JBond2010: this does not work for Server 2008. Seems to be completetly different approach.

I tested for Active Sync:

 Validating certificate trust for Windows Mobile devices.
  Certificate trust validation failed.
   Tell me more about this issue and how to resolve it
   Additional Details
  The certificate chain didn't end in a trusted root. Root = CN=thawte Primary Root CA, OU="(c) 2006 thawte, Inc. - For authorized use only", OU=Certification Services Division, O="thawte, Inc.", C=US
 

The cert I installed is definitely correct. Whats still wrong?

And: how can I install Remote Outlook using the Outlook 2010 Client?

Well, I found the solution finally:

First Server 2008 R2 must have the RPC over HTTP enabled:

Second under Exchange Management Right Click Client Access under Server Configuration and activate Outlook Anywhere.

After about 10 Minutes, the clients can access the Server using NTLM authentication.

Found out that rpc over http is not installed by default
