Outlook 2010 Disable Autodiscover

Outlook 2010 Disable Autodiscover

This is how we setup Outlook 2010 Disable Autodiscover feature. When you have an on premise Active Directory server with no Exchange server, you will find that configuring an Outlook client will not be possible with our hosted Exchange servers. Follow these steps to disable autodiscover from the registry fix that Microsoft has given.

Create a notepad file and paste the following below and save it as “outlook2010disableautodiscover.reg”.

[HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\AutoDiscover]

“ExcludeScpLookup”=dword:00000001
“PreferLocalXML”=dword:00000001
“ExcludeHttpRedirect”=dword:00000000
“ExcludeHttpsAutodiscoverDomain”=dword:00000001
“ExcludeHttpsRootDomain”=dword:00000001
“ExcludeSrvLookup”=dword:00000000
“ExcludeSrvRecord”=dword:00000001
