You’ll need to contact Microsoft for that information. Oh wait, it’s right there on the internet...


Microsoft 365 (Office) for Mac requires macOS Sonoma (14) or later to receive current feature and security updates (starting with update 16.101).

Microsoft has a policy of only supporting the three most recent versions of macOS.


Although the current versions of Office and 365 apparently will run on Sonoma, I wouldn't count on that lasting for long. The three most recent versions of macOS are now Sequoia, Tahoe, and Golden Gate. Which implies that the next time Microsoft updates Office or 365, they're likely to cut off any version of macOS before Sequoia.
