CDO 1.21 is not included with Outlook 2007 but can be downloaded from
http://www.microsoft.com/downloads/d...displaylang=en.

However, because CDO 1.21 is not supported in managed code, it's pretty
irrelevant to VSTO add-ins, which are the topic of this forum. You should
post any future Outlook VBA questions "down the hall" at
http://www.microsoft.com/office/comm....program_v ba.
