Office 365 installation issue on MacBook Pro with macOS Monterey

If so, it's "Christmas." This Microsoft Support article suggests that existing users can keep using Office 365 on Monterey – without feature or security updates. But it also says "Note that new installs of Microsoft 365 for Mac require macOS Ventura or later."

Microsoft Support – Upgrade macOS to continue receiving Microsoft 365 and Office for Mac updates

Try logging into the online/web version of Office365 as suggested by dialabrain, you just access the Office "apps" through any browser. Once you are logged into the Office365 web suite, then you may be able to click on your avatar for Office365 or maybe Settings (within the office web app) to download an older version of the stand alone Office apps compatible with Monterey. Sometime last year I saw an option for this, but I just took a quick look and didn't see it, but MS keeps moving things around so it is hard to say. This would be a question for the university's IT department.

There is a *possibility* you may be able to install Office 365 on Monterey.

The final version that was compatible with Monterey was Office 365 v16.89.1 (Sep. 17, 2024). You should be able to download the installer from Microsoft's Update History For Office for Mac. Scroll down to the line for Sep. 17, 2024 version 16.89.1 and download the installer package for Office Suite with Teams or without Teams, whichever you prefer. You should then be able to install it.

Make sure you have Monterey 12.7.6 installed before you install this version of Office 365.

Note (this is the "possibility" piece). You will still need an Office 365 license to activate the installation. There is a 1-month free trial available, so you could sign up for the free trial and see if you can activate your installation. If it doesn't work you can cancel the subscription before the end of the 1-month trial.

Please let us know if this works!

(Full disclosure ... I have not done this myself, so I cannot claim that it works; only that it is a possibility.)

You would have to acquire a new Mac or use an alternative office suite such as LibreOffice.

Just to add, Microsoft 365 online may work. You'll have to check.

Monterey is the latest version of macOS supported on your Mac.
