How to Install Microsoft 365 on macOS Monterey (Compatible Version)
Question details
The user needs to install a working version of Microsoft 365 on a Mac running macOS Monterey, avoiding newer builds that require macOS Ventura or later.

- Product
- Microsoft 365
- Device & OS
- macOS Monterey
- Scenario
- Installing Microsoft Office applications on an older MacBook that cannot be upgraded to the latest macOS.
- Observed behavior
- Standard Microsoft 365 installers and AutoUpdate prompt require macOS Ventura or later, preventing successful installation on Monterey.
Make sure you have your Microsoft account credentials ready and verify that you are currently running macOS Monterey (macOS 12) from the 'About This Mac' menu.
Clean Install the Compatible Version (Build 16.88)
Remove incompatible versions completely and manually install the specific Microsoft 365 package that officially supports macOS Monterey.
Microsoft periodically drops support for older macOS versions. As a result, the latest web installers will fail on Monterey. By clearing out existing apps and downloading version 16.88 directly from the Office CDN, you can bypass the block.
Open your Mac's 'Applications' folder. Locate all Microsoft applications, including Word, Excel, PowerPoint, OneNote, and OneDrive, and drag them to the Trash. Empty the Trash.
Visit the official Microsoft Office release history page for Mac, or use the direct Office CDN link, to download the Microsoft 365 version 16.88 installer package.
Double-click the downloaded .pkg file and follow the on-screen instructions to install the compatible Office suite.
When Microsoft AutoUpdate launches and requests to install a newer version requiring macOS Ventura, explicitly click 'Cancel' or ignore the prompt to keep your working version intact.

Frequently Asked Questions
Why can't I install the latest Microsoft 365 on macOS Monterey?
Microsoft policy only supports the three most recent major versions of macOS. Once newer macOS versions are released, older ones like Monterey no longer meet the system requirements for the newest Microsoft 365 builds.
What is the latest compatible version of Microsoft 365 for macOS Monterey?
Version 16.88 is the last officially supported Microsoft 365 build for macOS Monterey. You must download this specific version rather than using the default installer.
How do I stop Microsoft AutoUpdate from breaking my compatible installation?
When Microsoft AutoUpdate opens, uncheck the box for 'Automatically keep Microsoft Apps up to date'. Whenever prompted to install updates that require macOS Ventura, cancel the installation.
Can I still use OneDrive and OneNote on macOS Monterey?
Yes, but you must ensure you are installing the older, compatible versions of OneDrive and OneNote (bundled with the 16.88 package). If you attempt to download them directly from the Mac App Store today, they may require a newer macOS.
