Install a Compatible Older Version of Microsoft Office

Since Microsoft 365 only supports the three most recent macOS versions, installing a previous build (prior to 16.88) will restore functionality on macOS Monterey.

Microsoft periodically drops support for older operating systems to focus on the latest three major macOS releases. To continue using the desktop applications on an older MacBook, you must manually install an earlier release and prevent it from updating automatically.

1
Remove the incompatible version

Open the Applications folder on your Mac, locate the Microsoft Word application, and drag it to the Trash to uninstall the incompatible version.

2
Download an older Office installer

Visit the official Microsoft 'Update history for Office for Mac' webpage and download an installation package released prior to version 16.88.

3
Install the downloaded package

Double-click the downloaded .pkg file and follow the on-screen instructions to install the older version of Office.

4
Disable automatic updates

Launch Microsoft Word, click on 'Help' in the top menu bar, select 'Check for Updates', and uncheck the option to automatically keep Microsoft apps up to date.

Update Prevention: Disabling automatic updates ensures that Microsoft AutoUpdate does not overwrite your working older version with an incompatible newer build.

Frequently Asked Questions

Why does Microsoft Word say my macOS is unsupported?

Microsoft 365 for Mac policy is to support only the three most recent major versions of macOS. When Apple releases a new macOS, the oldest of the three loses support, meaning older MacBooks that cannot upgrade will be blocked from receiving new Office updates.

Can I keep using my older version of Word permanently?

Yes, you can continue using a compatible older version of Word on your Mac. However, you must disable automatic updates. Keep in mind that older versions will no longer receive new features or security patches from Microsoft.

Where can I find older versions of Office for Mac safely?

You should only download older installers directly from Microsoft. Search for 'Update history for Office for Mac' on the Microsoft support site to find direct download links to previous official releases.

Will I lose my documents if I uninstall the current Word app?

No. Uninstalling the Microsoft Word application from your Mac's Applications folder only removes the software. Your locally saved documents and files remain completely intact on your hard drive.
