Using classic Outlook for Windows in business environments
I created a user script to revert this change, until the feature is rolled back or made a user setting.
This is a hotfix script, I can't make any guarantees that it will work on every system, or if Microsoft changes the names of these elements on their end.

Anyone may feel free to edit and share this to improve it.
It's tested and working in Chrome and moves the quick actions back to the left, which is enough for me to get back to doing my actual job.
You can comment out Line 22 if you want to keep the delete quick action on the far right.
Hope this helps someone.
