And this is called in your Startup() event handler? And outlookExplorer is
declared at class level and not in the procedure? What you show looks OK to
me.

I usually test for something like this:

if(Outlook.ActiveExplorer() != null)
{
outlookExplorer = Outlook.ActiveExplorer();

// then I add the Explorer events
}
