WTF?!
You guys seem just dead-set on wasting my screen's horizontal space.
Everyone's still smarting from having to deal with the unwanted "apps" getting crammed onto the window on the right, we still don't have any assurance that the work-around will be preserved for those of us that would prefer not to have Microsoft use our screen to advertise their other products they want us to use.
But now the recent update to Outlook has added a vertical strip of message-handling buttons to the right side of the reading pane, yet again consuming horizontal space that I would much prefer be used for the triumvirate of folder navigation/message list/reading pane that works so well together.
I guess I should be thankful that at least I can still not have the apps, because otherwise the stealing of my horizontal space would be even worse. But I am still frustrated by this lack of respect for screen real estate.
For the love of all that is good, please revert this change or give us another checkbox to let us turn it off!
