It's not Outlook's fault.  Office, IE, etc. all use stunnel which, on XP/2003, 
is as outdated as OpenSSL 0.9.8.

Enable 3DES to support XP clients

and how does that give you any gain over RC4?s

The cipherspec given disables both. Given a choice, I'd rather have 3DES than RC4.

Umm... did you actually read those? That's a long, varied list of attacks on RC4, whereas 3DES is only vulnerable to the same attacks as all other CBC-mode ciphers. 112-bit encryption is still generally safe for at least a few more years. Well past the point where we don't have to worry about XP anymore.
