Hi,

In was trying to add button in inspector window. I
used .InspectorsEvents_NewInspectorEventHandler(myInspe ctors_NewInspector);
event and in this event I called a wrapper class where I configured
ItemEvents_10_OpenEventHandler(myMailItem_Open);

In this event I tried to create a button.

The problem over here is the button does not get created. However,
when I click on reply to this mail a new inspector is opened up where
I can reply to my mail and then a button on the reading inspector is
added.

I do not understand why this is happening.
