I've been using Microsoft 365 for a couple years on. Mac Monterey desktop and all of a sudden I've got a document that I'm working on for a months and can't edit the document? I am using Word and Excel on a Mac desktop. The Microsoft download is showing up in my folder but I don't see it in my applications and word document is still not working

Answer 1

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

Answer 2

Hello, thank you for reaching out to Microsoft Q&A.

Could you please let me know what versions of Microsoft Office 365 apps are installed on your device?

To check your Office version, launch an Office app, such as Word, and select About Word from the menu.

Note -

There was a notification from Microsoft yesterday (July 13) indicating that some users running Office apps on Mac may experience reduced functionality mode. To resolve this issue,

Try updating your Mac to the latest version.

To update, select Apple menu > System Settings > General > Software Update.

Note: Make sure your device is running macOS 12 Monterey or later.

If you are already running macOS Monterey 12 and don't see any updates there, update your Office apps.

Open any Office app such as Word or Excel, then select Help > Check for Updates. In the Microsoft AutoUpdate window, click Update All.

Once the updates are completed, restart the app.

Mostly updating the OS or the Office apps should resolve the issue.

If you are unable to update both the Office apps and macOS,

• Quit all the Office applications.
• Then, sign in again.
• That is, open any Office app, go to Account Settings > Click Sign out and then sign in again with your Microsoft account.
