For S/MIME implementation in Outlook 2010 / Windows 7, I want the users private key protected with password (high security : password is required for each encrypting / decoding action). I have set, without effect, the following registry keys : HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Cryptography <new DWORD Value "PrivKeyCacheMaxItems"=dword:00000000> HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Cryptography <new KEY "Protect" ; new DWORD Value "AllowCachePW"=dword:00000000> HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Cryptography <new DWORD Value "ForceKeyProtection"=dword:2> Any ideas ?

Hi, I would like suggest you post the issue to Windows Outlook Support forum for further help. Thanks for your understanding. Regards.Spencer TechNet Community Support
