Download a Compatible Build from Office Release Notes
Microsoft provides historical release builds that support older operating systems like macOS Catalina. You can manually download the last supported version.
Microsoft officially supports only the three most recent macOS versions for Office for Mac. For macOS 10.15 Catalina, the final compatible build is typically version 16.66. You will need to download this specific installer package instead of using the latest one provided on the main Microsoft website.
Open your web browser and navigate to the official Microsoft page for 'Update history for Office for Mac'.
Scroll through the release history list to find the October 2022 release (Version 16.66). This is the last version that officially supports macOS Catalina.
Click the download link for the Office suite installer package (.pkg) associated with version 16.66.
Once downloaded, double-click the .pkg file and follow the on-screen instructions to install the software on your Mac.
