Frequently Asked Questions

Can I activate Office 2016 with a Microsoft 365 subscription?
No, a Microsoft 365 subscription is a separate product. To activate Office 2016, you must sign in with the specific Microsoft account that holds the original standalone Office 2016 purchase license.
What is the final version number for Office 2016 on Mac?
The final supported build for Office 2016 for Mac is version 16.16.27. Updating to this specific version resolves many ongoing activation and compatibility bugs.
