You no longer have to call apps like Word, Excel, and PowerPoint with the “Online” branding if you’re using the web apps. The company plans to drop this for its Office Online suite of apps. It does make sense to just drop the Online name, since using it through the web basically means you are online. However, this might cause some confusion when Microsoft tries to differentiate the web version from its desktop and mobile apps. Microsoft said it’ll just call them “Office for the web” to clarify things, which if you think about it is what the Online name did for them anyway. That said, other Microsoft products will still hang on to the Online descriptor. These include Exchange Online, SharePoint Online, Project Online, and Office Online Server.
