Microsoft released a new Insider Preview build of Office Mobile for Windows 10 this week, bringing the version number to 17.7571.xxxx. The update was released on the 11th, although it wasn't announced until last night.
New Previews are generally offered monthly, with the last one being made available on October 6. The November update includes a number of new features for all of the apps in the Office suite, which are Word, Excel, PowerPoint, and OneNote. Here's what's new:
Accessibility built right in to Office Mobile We have improved support for using Narrator and other assistive technologies as well as your keyboard to edit documents with others, sort data in worksheets, read and edit presentations, and more.
Sharing Notifications in Word Mobile, Excel Mobile and PowerPoint Mobile* No need to keep checking your shared documents, workbooks, or presentations. We'll send you a notification when there's activity. *This feature is available with an Office 365 subscription only.
Open more file types with Excel Mobile You can now open more file types than you before, such as files that contain snapshots from your Camera tool.
Page background colors now in OneNote Does your OneNote page need a change? Switch it up by adding a background color in just one click and change the mood of your page.
Lasso Select now at your fingertips with PowerPoint Mobile The Surface pen button allows you to use lasso select on ink without visiting the ribbon.
Use your Pen to select and change objects in PowerPoint Mobile* Grab object handles with the Surface pen to resize, rotate, move, and more. *This feature is available with an Office 365 subscription only.
To sign up for the Office Insider Program on Windows 10 (all platforms have different steps to take), you'll need to have opted into the Windows Insider Program, and you'll need an active Office 365 subscription. If that sounds like too much, you can always wait a few weeks until this update hits the Production channel (non-Insiders).
