Hi to all, I've an issue probabily due to a misconfiguration error in autodiscover configuration. I'll explain my environment:
simple single server 2012 R2 with Exchange 2016 on it. Created a split zone dns for internal mybusiness.com in forward lookup zone for resolving DNS names (autodiscover ad externale name). Changed all virtual dirs (internal and externals with same name exchange.mybusiness.com) and also autodiscover with this command
Set-ClientAccessServer -Identity myserver -AutoDiscoverServiceInternalUri https://autodiscover.mybusiness.com/Autodiscover/Autodiscover.xml
Created also external DNS records (autodiscover.mybusiness.com and exchange.mybusiness.com) pointing to my public ip where my server is located and opened 443 tcp forwarded to the server. Using internal CA with a certificate containing only exchange.mybusiness.com and autodiscover.mybusiness.com. If I've done mistakes please tell me. Now, the client problem.
Using an off domain client with Outlook 2016 (also with Outlook 2013) and autoconfiguration give the error "unable to find activesync EAS" error...if i modify this registry key
HKEY_CURRENT_USER\Software\Microsoft\Exchange
DWORD = MapiHttpDisabled
Value = 1
it works without problems...Can anyone tell me why? and if i've done somekind of error configuring my environment?
Thank you all...
