Solution 1Recommended

Test with a New Mac User Account

Determine if the error is caused by a corrupted user profile on your Mac.

Sometimes, user profile corruption on macOS can interfere with Microsoft Word's ability to open files. Creating a fresh user account helps isolate whether the problem is systemic or profile-specific.

1
Open System Settings

Click the Apple menu in the top-left corner of your screen and select 'System Settings' (or 'System Preferences' on older macOS versions).

2
Add a New User

Navigate to 'Users & Groups', click 'Add Account' (you may need to enter your administrator password), and create a new standard user or enable the Guest account.

3
Log In and Test

Log out of your current account, log into the newly created account, open Microsoft Word, and attempt to open the problematic document.

Test with a New Mac User Account
Profile Corruption Identified: If the file opens successfully in the new account, your original Mac user profile may be corrupted. You can migrate your files to the new profile or contact Apple Support for profile repair options.

Frequently Asked Questions

Why does Word for Mac say 'Operation Canceled' when opening files?

This error often occurs due to corrupted Mac user profiles, syncing issues with large files stored in OneDrive, or deep-seated conflicts within the Microsoft Word application installation.

Will reinstalling Microsoft 365 fix the 'Operation Canceled' error?

In many cases, completely uninstalling and reinstalling Microsoft 365 from the App Store does not resolve this specific error, especially if the root cause is tied to a corrupted macOS user profile or an ongoing OneDrive synchronization bug.

Can I recover a Word document that won't open on my Mac?

Yes, you can often recover the content by opening the file on another device, logging into a different Mac user account, or opening it in an alternative word processor like Apple Pages or WPS Office.
