Needless to say, if you continue to run Microsoft Office app on macOS 10.13 or older, everything is supposed to work just like before, only that no other improvements are released. Not to mention that doing this comes with major security risks, as the vulnerabilities found in the productivity suite would no longer be fixed, leaving your device and data exposed to possible attacks.

“As new major versions of macOS are released and older versions become unsupported, we highly recommend you continue to update your macOS to a supported version in order to receive mainstream support such as security updates as well as new features (if you’re an Microsoft 365 for Mac subscriber).
