Ever since I started using outlook 365, the outlook option under send form has gone missing on Quickbooks Pro desktop 2016, and then I recently upgrade to Quickbooks Pro desktop 2019, it is still missing.  

I have already tried all 8 solutions here: https://quickbooks.intuit.com/community/Help-Articles/Outlook-is-missing-in-QuickBooks-Desktop-Send-... 

but none of it fixed the problem.

Do anyone have the same problem? or can provide help?
