Autodiscover takes long time Outlook

Autodiscover takes long time

When Outlook connects to an Exchange 2016 server it can happen that autodiscover takes long time when setting up a new profile. ( … up to 20 minutes )

This can be solved by implementing the following 2 registry keys on the PC running the Outlook client. ( Outlook should be closed )
Please choose the appropriate Office version when navigating down the registry path. ( this example is for Office 2013 = 15.0 ) :

HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Outlook\AutoDiscover
DWORD 32 bit ExcludeHttpsRootDomain  1
and
DWORD 32 bit ExcludeHttpsAutoDiscoverDomain 1

Office Versions :
2010 = 14.0
2013 = 15.0
2016 = 16.0

The annoyance that autodiscover takes long time will be gone with these registry entries.
