Outlook 2013 and Autodiscover

Hello!

After installing the second CAS/MB Exchange 2013SP1 server in my test lab I changed Outlook Anywhere internal and external names to mail.enterpise.local:

...but Outlook still gets from Autodiscover the CAS name = Exch1 (if I set Outlook proxy manually to mail.enterprise.local it's get changed to Exch1.enterprise.local next time Outlook starts):

[PS] C:\Windows\system32>get-outlookanywhere

Why Autodiscover still points to Exch1?

Thank you in advance,
