VSTO - Market Share of Outlook 2003 (Pro)? "Tadwick" <simon[ at ]schemax.com> 7/30/2006 4:14:03 AM I'm not convinced that I should be developing with VSTO yet. Does anyone have information on how many Outlook users are running the 2003 professional version (ie MS Office 2003 Professional Edition or MS Outlook 2003 Stand Alone) versus other versions of Outlook (ie MS Office 2003 Standard Edition or previous versions of Outlook eg XP, 2000 etc). Thanks, Tad
