What is the correct way to use launch mailto: with an attachment? I tried this and complains about an invalid switch.
set var vcmd = 'launch ''mailto:CPO?subject=[3]10 Yr&Body=CPO , %0D%0A %0D%0A I am showing that you have signed up for the attached event. %0D%0A %0D%0A Please open the attachmentand click Save and Close %0D%0A Thanks, %0D%0A CPO&attachment=""c:\temp\TestFile.txt""''' I tried this and it opens the mail message but without the attachment. set var vcmd = 'launch ''mailto:CPO?subject=[3]10 Yr&Body=CPO , %0D%0A %0D%0A I am showing that you have signed up for the attached event. %0D%0A %0D%0A Please open the attachmentand click Save and Close %0D%0A Thanks, %0D%0A CPO&attachment=''file:///c:/temp/TestFile.txt'''
