I'd be happy to accept this if that were true.  But I have two other computers using the same version of latest version of Outlook 365 Desktop and QB sends emails from them just fine.  

BTW, i would be more than willing to buy Software that is updated.  However, QB is one of maybe 50 pieces of software that I use, and QuickBooks is the single most unadvanced and unimproved softwares of all of my engineering and office software.  I've been using since 2005, and the bugs that were there back then continue to bugs today.  There is virtually nothing in the program that has made upgrading worth a single penny.  Really, the only reason for upgrading is so I can call support every 5 years when I have bug that shows up that keeps me from working.  Errr.
