When creating Contact Lists in Outlook 2011 or 2016 for Mac the groups are local to the machine and not saved. When doing it on the web portal the list doesn't show up when creating an email, and the only way to access it is to start at the People list, and generate an email from the record. And it doesn't show up in my phone contacts. So its not particularly useful to even have it-not sure what the point is. But what I'd like to have is a group of contacts that I can easily select for email and modify as needed. Other services do provide this, so its definitely feasible. But maybe I'm misunderstanding how to implement it. 

And if I'm not, well, that needs fixing.
