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

@greed. The minions at Microsoft cannot leave well enough alone. When something works, it does not need to be "improved" because they cannot make enough changes to justify a new version. 

The office suite is fabulous and great. For the majority of users, these changes only alienate simple users who probably use less than 5% of the features.

Things like a new default theme with absurd colours, different (and worse) icons for ribbon items and menu realignments HURT more than improve the product.

Please leave these things alone.

OR

Make them customizable so the smart users can control their environment.
