Microsoft announced the Office Insider program back in November last year. Since then, over one million Insiders have used beta builds of Office apps across platforms. Microsoft today highlighted that Office Insiders have provided more than 100,000 pieces of feedback and it has helped them ensure a high-quality Office experience for all Office 365 subscribers worldwide.
Microsoft is announcing today that they are adding a new level called Office Insider Fast for Windows desktops, Mac and Windows Mobile (Android and iOS coming soon). This is similar to Windows Insiders Fast Ring, Office Insider Fast provides even earlier builds of Office, more frequently. This new program will be available in the next few days for Office 365 Home and Personal subscribers.
