Users are starting to see a new app bar in Outlook on the web, on the left size of the window, not at the bottom of the folder list – and it has buttons for the online versions of the Office apps.
Office 365 Premium subscribers should be familiar with the app bar in this position as they’ve had it on the left for many months, but not with the Word, Excel, OneNote and Powerpoint icons.
Microsoft is adding the icons for the online apps and moving the app bar to the left for everyone, both premium subscribers and free accounts.
This is a new design and cannot be disabled; the app bar cannot be moved to the bottom of the folder list.
Lame. This is dumb.
