Microsoft recently announced the new “Fast” level for the Office Insider Program where the company will release new update frequently. Similar to Windows 10 Insider Fast builds, these Office Insider Fast builds will also have quite a few bugs, and that’s expected — however, you get to try our new features before anyone else. Today, the company is releasing the first Office Insider Fast build for Office 2016 on Windows. Now don’t get too excited as the update doesn’t introduce any major updates. But it does bring a new feature called “Share with Me” which basically allows you to access Word files that were shared with you.
Microsoft states that if you are already an Office Insider, you can enrol into the Fast level by heading over to File > Account — from there, click on the Office Insider button and Change Level. You can enroll into the Insider Fast level from that dialog, and once that’s done, just check for updates to download the latest build (16.0.7329.1000).
