Just installed the latest batch of updates for my Mac office. When starting Outlook again, I was greeted with an invitation to try the new Outlook – https://techcommunity.microsoft.com/t5/outlook-blog/enhanced-performance-designed-for-simplicity-the-new-outlook-for/ba-p/1675505
When accepting it warned me about my Amazon WorkMail account not being supported (even though it is Exchange compatible)!!
Is the new Outlook only for Office 365 users?
