Using classic Outlook for Windows in business environments
I highly recommend everyone to leave feedback within the outlook .live.com page.
Within the email page click your profile picture on top far right, click "my profile", click feedback (should be bottom right).
Leave the feedback, and complain about how much longer it takes to access the quick action buttons, how the placement now makes it prone for mistakes and how the change has made using QAB no longer user friendly.
The more of us that flood the leave feedback / complain using the feedback feature the quicker it will be reverted and Microsoft will realize what a silly change it was.
Changes should add functionality and ease of use to the user experience and not the opposite.
Thank You all!
