strange problem connecting Outlook 2013 and Kolab 3.4 (ActiveSync)

correct!

I modified the local hosts file with these entries
---8<---
 192.168.1.206   dmzserver1.mydomain.de mydomain.de www.mydomain.de
---8<---
but the behavior is still the same. My only explanation is that Active
Sync is not using the client machine's DNS-resolution.

Could it possibly be that Active Sync is connecting to a
Microsoft-server to resolve the server name?

 best regards
