It didn't work for me on Ms Outlook 2016, I did every single step on the internet, but whenever I click a new email, no "From" only "To" shows, so I can't change the primary email and send from an alias instead. I even tried deleting the profile and re-creating
a new one to make sure the profile wasn't damaged, still same result, only a waste of time. I even added an alias as a separate email and sent test emails using it, and emails arrive sent from the primary email, not the alias. So frustrating!!! The function
is there, in Ms Mail App which is free and has way fewer functions, but not in Ms Office Outlook Professional 2016. They can push it as an update to Ms Office Pro 2016 so professionals can do their work with ease, but, no, just let them suffer and turn to
Office 365, and instead of doing my work, I am here looking for a solution which is not there. so everytime I need to send an email from alias, I have to go to a browser, and send it from Outlook.com. the Free app has the function but a paid Office Pro 2016
does NOT.
