I don't think there's a difference in compatibility unless you're supporting
Outlook 2000.

I have no idea what you mean by the dispid's for those events, or why you
would need that.

Activate gets called many times. It may fire 2 or 3 times the first time the
item is activated, and then each time the focus returns to that item. Just
use a flag to test for the first Activate or to test for the UI having been
created. Since there are also cases where that first Activate will not fire
you usually back that up with a check in a handler for OnSelectionChange,
which will fire in those cases and there you also check for the UI creation.

Couple questions:

1) Should I use InspectorEvents or InspectorEvents_10? I.e., which one
ensures maximum compatiblity?

2) What are the dispids for Activate, Deactivate and Closed?

3) Does Activate get called multiple times for a specific mailitem?

Thank you,
