I am experiencing an activation problem with my Microsoft 365 subscription on macOS. My MacBook Air running macOS 12 cannot install or activate the latest Office apps, leaving my paid subscription unusable. I need a practical solution, such as a compatible offline Office license, a downgrade option, or an adjustment to my subscription. Please advise on how I can continue using Microsoft Office on my current device, since the current activation requirements are not supported.

    For macOS Monterey 12, Microsoft 365 is no longer supported for current updates.

    The August 2024 release, version 16.88, was the final Office build supporting Monterey. An existing installation may continue to work, but it will not receive security updates, fixes, or new features. Current Microsoft 365 and Office 2024 installations require macOS Sonoma 14 or later.

    You will need to uninstall it. And install the downgraded version (16.88) here: https://officecdn.microsoft.com/pr/C1297A47-86C4-4C1F-97FA-950631F94777/MacAutoupdate/Microsoft_365_and_Office_16.88.24081116_Installer.pkg?apid=ets
