You seem to have it solved now, but for things like that I use the
Redemption library that Dmitry mentioned in his post. It does everything CDO
did and a whole lot more.

Ken,

thank you for your quick answer, but now if you want to create an add-in
for
Outlook 2003/2007 which changes the color labels of the appointments in a
calendar, what is than the best way to solve this (I want to use .NET to
create the plug-in, but CDO 1.21 is not supported...)?

Thank you in advance,
