Disable Auto Discover in OUtlook 2010 to eliminate certificate mismatch error

I keep getting a certificate mismatch error when Opening Outlook 2010. Is there a way to disable autodiscover so I don't get that message. My domain is a .local domain. I have a certificate for my internet based clients so they have no issues. I can't rename my domain since Exchange 2010 doesnt' support it. I don't need autodiscover since I manually configure my clients. I just want to permanently turn it off.

To disable an auto discover, you can use these regkeys: -

•      HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\14.0\Outlook\AutoDiscover\ExcludeSCPLookup = 1

•      HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\14.0\Outlook\AutoDiscover\ExcludeHttpRedirect= 1

•HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\14.0\Outlook\AutoDiscover\ExcludeHttpsAutodisoverDomain = 1

•      HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\14.0\Outlook\AutoDiscover\ExcludeHttpsRootDomain = 1

•      HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\14.0\Outlook\AutoDiscover\ExcludeSrvRecord = 1

I also try all these on my system and it work. I hope it will also prove helpful for you.

Place a DENY on the SCP objects in AD and just not publish the DNS records until the migration coexistence is complete.

You can use ADSIEdit for that.

I can't understand why these registry changes don't work for me. Does it only work sometimes? Please help!!!
