List conditions for displaying the "New Outloook" switch. I'm on 16.33 (19112700) and don't have the option.
I'm on insiders fast, on Outlook version 16.33 (1911270) on Catalina 10.15.2, and there's no New Outlook switch, and the option isn't in "Help" either. If there conditions in which it's not available, that would have been good to know before updating to insiders fast.
Support article with requirements is here: https://support.office.com/article/6283be54-e74d-434e-babb-b70cefc77439
Same here, all of a sudden I lost the option to switch to the new UI without any changes from my side
Thanks for the link. However as mentioned, I've met all of the above requirements, and do not have the switch that the article suggests that I should be able to see.
