Outlook 365, how to go back to OLD ribbon graphics and icons

VasilMichev and adam deltinger - we've just been forced onto Office 365 as part of a corporate roll out today. Every single person in my office *hates* the new configuration, layout, colour scheme, design, everything. It's not an adjustment issue. I can handle updates to software where things remain workable or where things are improved... In fact, I welcome those improvements. What MS has done with Office 365 is not an improvement in the slightest. You've yet again moved/changed/removed useful features that everyone was accustomised to. You've introduced things that don't actually help or accomplish anything meaningful. It's like you've pulled the rug out from underneath all your customers because someone thought the rug-size was an inch too long, and then vomitted over said rug. It is so clunky, unintuitive, ugly, uncustomisable, and looks like it is from 1995. It's undone preferences and saved options. It even auto-updated while I was in the middle of using the PC without any warning. It's like a seventh circle of hell. How does someone execute something so poorly, and have it endorsed? Whoever ultimately approved the Office 365 changes should be fired and sent to a remote, gangrenous island to spend the rest of their life in squalid exile, forced to contemplate how much harder they've just made everyone's lives.
