I tested this setting with Outlook 2007 on Win 7 and they worked fine. Is
it possible that you're testing from WinXP? -- Then this is a known issue:
The WinXP crypto stack does not support any of the current ciphers.

In case you plan to continue supporting WinXP although it is end of life,
you need to make the choice on which very old cipher you want to enable.
