As the Insider program matures we will expand to two levels of Insider – Office Insider Slow and Office Insider Fast.

Office Insider Slow – Best for Insiders who want to get early access to fully supported builds with minimal risk and provide feedback to make Office great.
Office Insider Fast – Best for Insiders who want to use the earliest preview builds to identify issues, provide feedback to make Office great and don’t mind a bit of risk using unsupported builds. By choosing the Fast option, you agree to the program’s terms, which supersede your agreement with Microsoft to use Office.

Insider Fast is available now for Office 2016 for Mac, with other platforms rolling out in the next few months. You can opt in to Office Insider Fast for Office 2016 for Mac through Microsoft AutoUpdate.
