Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
For macOS Monterey 12.7.6, the last supported Office build is 16.88.
Use this installer package: Microsoft_365_and_Office_16.88.24081116_Installer.pkg
If Help > Check for Updates is missing in the current app, install Office 16.88 directly with that package.
After installation, open any Office app and, if available, run Help > Check for Updates once to get the final 16.88.x release for Monterey.
If the Mac can be upgraded, Microsoft recommends updating macOS first. Current Office updates require a newer macOS version, and if the device cannot be updated, options include using Microsoft 365 on the web or installing Office on another supported device.
