When setting up the automatic reply and out of office from your Outlook 2010 having Exchange 2010 you might have the problem with a pop-up saying “Your automatic reply settings cannot be displayed because the server is unavailable”.
I have managed to solve this with a DNS record in your infrastructure. Create the following SRV record to fix the issue.
Service: _autodiscover
Protocol: _tcp
Port Number: 443
Host: myexchangeserver.mydomain.local
On the client PC run the following to refresh the DNS. Make sure you run the CMD as Administrator
ipconfig /flushdns
ipconfig /registerdns
This should fix the problem and the user will be prompted to enter his Out of office settings.
