Thanks,


It sounds like you're not subscribing to the correct Explorer's events and
but also i subscribed to FolderSwitch, and SelectionChange events, and
they fires well.

that you're not using a wrapper collection for open Explorers. If you were
you wouldn't get Close on the first Explorer after opening a second
Explorer.
Sorry probably i didn't explain right my problem, but if open another
explorer (NewWindow) on this just opened explorer
on closing it teh Close event will fire. On main explorer (explorer
that i get when Outlook is starts) i never get close event.


Are you getting ActiveExplorer and subscribing to that in the Startup event
handler in your VSTO addin?
Yes that exactly what i'm doing.



Any other suggestions??, Things that i should check??


Thanks in Advance.
