Some of our clients have issues with the Sign In client for Exchange Online and I'm trying to follow this KB http://support.microsoft.com/kb/972654 but one of the settings I need to adjust isn't there.
Where can I find the setting below? There's a bunch of other "Network access"-settings, but just not this one:
Network access: Do not allow storage of credentials or .NET Passports for network authentication
(I'm using Windows 2008 R2)
