We are opening an Excel workbook through a hyperlink. The workbook contains VBA code that opens a Microsoft Outlook "Send Message" dialog box. The macro works fine when we open Excel and run it, but it won't work when we run it through the browser. The message we get is "Unable to get the Show property of the Dialog class". The code used is: Result = Application.Dialogs(xlDialogSendMail).Show(Range(" A1"), "Subject")<BR><BR>Thanks for your help.
