I have an add-in that displays an additional command bar in the Outlook main (Explorer) window. The command bar has a button that is enabled when exactly one email is selected in Explorer view, and disabled otherwise. I do the following sequence: click on an email: button is enabled; click on a group header such as "Today", "Yesterday", etc: button is disabled; click on an email again and so on. After a few tries I can see that a few seconds pass between clicking on an email and button getting enabled. As if there's some delay between the button gets enabled and repaints itself. I can see that SelectionChange event of the Explorer objects fires on time, immediately after email is clicked. It just takes time for the change to become visible. An interesting observation: there's a OneNote button on the Outlook toolbar created by the Microsoft's own OneNote add-in. This button exhibits exactly the same problem! At the same time I have OutlookSpy installed, and its buttons do not exhibit this problem. Any ideas? Thanks a lot, Leonid Back to top Dmitry Streblechenko Guest Posted: Sun Mar 25, 2007 2:00 am    Post subject: Re: Delayed CommandBarButton.Set_Enabled from SelectionChang OutlookSpy enables/disabled its buttons based on the ECE callbacks rather than OOM events.

Using this technnique I have overcome my problem, or so it seems now.
