On macOS Monterey 12.7.6, Microsoft 365 apps are supported only up to Office for Mac version 16.88/16.88.1 (and, per later guidance, 16.89 dated September 10, 2024). Newer builds require macOS Sonoma or later and will not install.
To get Microsoft 365 working on macOS 12.7.6:
- Make sure there is a valid Microsoft 365 or Office 2021/2024 license associated with the account. A current license is required to activate the older build.
- Download an older Office for Mac build that supports Monterey (for example, 16.88 or 16.89) from the Office for Mac update history page listed in the context:
- Use the long table of downloadable versions on the update history page to select version 16.88 (or 16.89) for Office for Mac.
- Install the downloaded package on macOS Monterey 12.7.6.
- After installation, open any Office app and sign in with the licensed Microsoft account to activate.
- Run Help > Check for Updates once to move to the final supported build for Monterey (for example, 16.88.1 for Outlook and PowerPoint). AutoUpdate does not need to remain enabled because there will be no further updates for Monterey beyond that version.
If upgrading macOS to Sonoma or later becomes possible, newer Microsoft 365 builds can then be installed and updated normally.

Trying to create a bootable installer with the latest, all the download sites I've tried with the CDN link say Not Authorized with error 403
https://swcdn.apple.com/content/downloads/34/21/062-40406-A_GZQ27OUQER/ggclib72ow1omcvfexvp84bc9x5ei5tyqu/InstallAssistant.pkg
.
I have the installer app for 12.7.4 but after installing + booting, I still have to manually Update to 12.7.6, which is over 1GB download
.
So I have a 2018 Mac Mini updated in-place to 12.7.6 but cannot download the latest 12.7.6 directly to make a bootable installer.
.
Trying to download from Terminal gives me this:
softwareupdate --list-full-installers
