How to Fix Microsoft Office 2011 AutoUpdate Errors on Mac

Product: Microsoft Office for Mac 2011, Microsoft AutoUpdate
Device & OS: Mac
Scenario: Encountering update errors when Microsoft AutoUpdate attempts to check for updates on unsupported Office 2011 software.
Observed behavior: Microsoft AutoUpdate continues checking legacy Office 2011 applications, resulting in recurring update errors because the software reached end of support in 2017.

Before you start

Check your Mac's Applications folder to verify if you have multiple versions of Microsoft Office installed, specifically the legacy Office 2011 version.

Solution 1Recommended

Remove Legacy Office 2011 Applications

The best way to resolve AutoUpdate conflicts is to completely uninstall the unsupported Office 2011 applications from your Mac.

Microsoft Office 2011 for Mac reached its end of support on October 10, 2017. Keeping multiple versions of Office installed can lead to update and application conflicts. Removing the outdated version stops Microsoft AutoUpdate from checking it.

Quit Office Applications

Ensure all Microsoft Office applications, including Word, Excel, PowerPoint, and AutoUpdate, are completely closed.

Open Applications Folder

Open Finder on your Mac and navigate to the Applications folder from the sidebar.

Move to Trash

Locate the Microsoft Office 2011 folder, drag it to the Trash, and empty the Trash to permanently remove the legacy applications.

Conflict Prevention: Removing the 2011 version ensures AutoUpdate will only scan and update your currently supported Office applications.

Solution 2

Ignore the AutoUpdate Error

If you still need to use Office 2011 for specific tasks, you can choose to simply ignore the update errors generated by Microsoft AutoUpdate.

Frequently Asked Questions

Why does Microsoft AutoUpdate still check for Office 2011?

Microsoft AutoUpdate scans your Applications folder for any installed Microsoft products. If the Office 2011 folder is still present, the updater will automatically attempt to check it, even though the software has been officially discontinued.

Can I use Office 2011 and a newer Office version at the same time?

While it is technically possible to have both installed on your Mac, it is highly discouraged. Running multiple versions often creates file association issues, application conflicts, and persistent AutoUpdate errors.

Is Microsoft Office 2011 still safe to use on Mac?

Office 2011 reached its end of support in October 2017. Because it no longer receives security patches or bug fixes from Microsoft, continuing to use it poses a potential security risk to your computer.

How do I turn off Microsoft AutoUpdate completely?

You can disable automatic updates by opening any supported Office application, clicking 'Help' > 'Check for Updates' in the top Mac menu bar, and unchecking the 'Automatically keep Microsoft Apps up to date' box.
