Hello Office for Mac Insiders,
We have released the first drop of a fully 64-bit version of Office 2016 for Mac to the Insider Fast channel! The update number is 15.25 (160630). I do encourage Insider Fast users to install this update and give it a test. We want to know about any problems you encounter as soon as possible, so that we can make sure we address them before the official release.
This is a huge update for Office and something that we have been working towards for a very long time. I’m thrilled to finally have it available for testing!
The Insider Fast channel is intended for early adopters and those wanting the earliest view into upcoming releases, and the 64-bit version will progress to the Insider Slow channels and to widespread publication over time. I can’t speak to a specific date for that wide release for you yet, so please send us your feedback as soon as you can.
To learn more about the move from 32-bit to 64-bit Office, including information about add-ins, see Mac Office and the Transition to 64-bit. For details about the Insider Fast program, including options for getting in touch or reporting bugs, see Announcing Office Insider Fast for Mac Insiders.
