Today we’ll talk about an error that occurs when we are testing Outlook Connectivity with https://testconnectivity.microsoft.com/
See the images bellow, this can be your error:
We find a lot of things, but without sucess…..
An important thing…. this scenario is an Exchange Server 2007…
We allowed the ports 6001-6004, checked the Address Book, checked the Firewall rules, rechecked virtual directories, autodiscover, disabled ipv6 through nic and the error was there…
But… we think… we disabled the ipv6 through NIC only and through regedit?
After disable the ipv6 through regedit, we have sucess in tests and in Outlook configure….
reg add HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\ /v DisabledComponents /t REG_DWORD /d 0xff /f
