I downloaded MS Office 2024 onto a new MacBook Pro after I completed data migration. It initialized and then it went through the process of checking for updates. Outlook would not update. It said there was a "Check error: Installed Nov 16 2022." How do I fix this? Power Point, Excel, Word all updated.

    Hi Stephen,

    It appears the data migration may have carried over an older Outlook installation from 2022, while the other Office apps were replaced successfully.

    First, quit Outlook. Download the latest standalone Outlook installer from Microsoft’s Office for Mac update history page and install it directly. Microsoft provides separate Outlook installation and update packages, so you do not need to reinstall the entire Office suite.

    If the installer still detects the old version, move Microsoft Outlook from the Applications folder to the Trash, restart the Mac, and then run the standalone Outlook installer again.

    Please let me know how it goes after trying these steps, and I'll be glad to continue looking into it with you.

    On Mac, start with Outlook itself and Microsoft AutoUpdate:

    1. Open Outlook.
    2. In the menu bar, select Help > Check for Updates.
    3. When Microsoft AutoUpdate opens, select Update or Update All.
    4. After the update finishes, restart Outlook.

    If Outlook still shows a check error:

    1. Close all Office apps.
    2. Open Microsoft AutoUpdate directly from Finder > Applications > Microsoft AutoUpdate.
      • If it is not there, check /Library/Application Support/Microsoft/MAU2.0/.
    3. Review the available updates, then select Update next to Outlook or Update All.
    4. After updates complete, launch Outlook again and test.

    If the Mac is on an older macOS version, Office 2024 may not update correctly. For macOS devices that cannot take the required updates, the documented path is to use a supported device or upgrade the device/OS. A related known issue also affected Microsoft 365 for Mac users in the Beta channel where apps stopped being offered updates at versions 16.78 or 16.79; the fix was to install Outlook for Mac 16.79.23101801 or later.

    If Office 2024 is installed but the app still appears as an earlier version in the app backstage, install the latest Office updates first. If that does not resolve it, Microsoft documents deleting %LocalAppData%\Microsoft\Office\Licenses\5 and then reopening an Office app to sign in again. This step is for the documented Office 2024 version-display issue.
