ThisAddIn_ShutDown doesn't execute

Question

In my add-in for Outlook, I have the following lines.

private void ThisAddIn_Startup(object sender, System.EventArgs e)
{
  MessageBox.Show(\"Hazaa!\");              


        

Answer 1

If you are using Outlook 2010 you can ask Outlook to inform your plugin when it is shutting down.

[RequireShutdownNotification]=dword:0x1

The Key has to be placed in the Registry Folder of your Plugin

Answer 2

Are you using Outlook 2010?

Starting in Outlook 2010, Outlook, by default, does not signal add-ins that it is shutting down. Specifically, Outlook no longer calls the OnBeginShutdown and OnDisconnection methods of the IDTExtensibility2 interface during fast shutdown. Similarly, an Outlook add-in written with Microsoft Visual Studio Tools for Office no longer calls the ThisAddin_Shutdown method when Outlook is shutting down.
