In a moment of levity to lift the current situation, we discuss the wide range of themes offered by Office 365 to users. People can choose from 49 different themes to customize the online apps. You can go crazy with something like Super Sparkle Happy, display your love of cats, or choose a simple color. Once chosen, you should see the same theme across all the Office online apps. Except Teams, which does its own thing.
At the Microsoft Ignite 2019 conference, Microsoft described how SharePoint Online will use Office 365 compliance features such as sensitivity labels and information barrier policies to better protect information stored in SharePoint sites. The Office Online apps also gain support for sensitivity labels. The new features will enter a mixture of public and private previews starting November 20.
