Hi Stephen,

I'm involved in a MAPI project using the wrapped PST sample as the basis of the approach. We have begun testing with the technical preview of Outlook 2010, and noticed a crash when mousing over recipients as Outlook shows its new info tooltip.  I downloaded the latest of the sample from this site to see if it had the same problem, and discovered that it does indeed.  I have raised an issue in the tracker (#3790), with some additional information.

Thank you very much for your support on all things MAPI, and the sharing of your vast and detailed knowledge.

Nick.
