Fix OneDrive Files Corrupted When Shared from a Mac
Question details
OneDrive files shared from a Mac cannot be opened by recipients because they appear corrupted, even though the same files work perfectly when transferred via USB.
- Product
- OneDrive
- Device & OS
- Mac
- Scenario
- Sharing a large folder of files with other users via OneDrive on a Mac device.
- Observed behavior
- Recipients receive corrupted or unopenable files. The issue stems from the synchronization, uploading, or downloading process rather than the source files being inherently damaged.
Ensure your Mac has a stable internet connection and wait for the OneDrive desktop application to display a 'Up to date' status before sharing any links.
Restore Your OneDrive to a Previous State
Use the built-in OneDrive Restore feature to roll back your entire OneDrive to a time before the file sync corruption occurred.
If an interrupted sync or malware caused widespread corruption in your shared folders, you can undo all actions that occurred on any files and folders within the last 30 days. This feature is particularly effective for Microsoft 365 subscribers or work/school accounts.
Open your web browser, navigate to the OneDrive website, and sign in with the correct account associated with the corrupted files.
Click the gear icon (Settings) in the top right corner of the screen, then select 'Restore your OneDrive'. If you are using a work or school account, it will be under Settings > Restore your OneDrive.
Choose a date from the dropdown menu (e.g., 'Yesterday' or 'Custom date and time') that corresponds to a time before the files became corrupted.
Review the activity chart to identify when the unwanted changes happened, select the specific activities to undo, and click 'Restore'.
Compress Mac-Specific Files Before Uploading
ZIP Mac-specific package files (like iMovie libraries) to prevent them from becoming corrupted during the OneDrive sync process.
Check Sync Status and Re-upload
Verify if a sync interruption caused incomplete file uploads and manually re-upload the affected files.
Try WPS Office for Seamless File Sharing
If you frequently experience cloud sync errors or file corruption with other platforms, consider switching to WPS Office. It provides a lightweight, all-in-one workspace with built-in WPS Cloud, ensuring stable and secure file sharing across Mac, Windows, and mobile devices.
- 1. Download WPS Office: Visit the official WPS website to download and install WPS Office for Mac.
- 2. Save to WPS Cloud: Open your documents in WPS Office and save them directly to the built-in WPS Cloud for secure backup.
- 3. Share with Confidence: Click the 'Share' button in the top right corner to generate a secure sharing link for your recipients.
Frequently Asked Questions
Why do my Mac files work on a USB drive but get corrupted on OneDrive?
This usually indicates an interruption during the synchronization or upload process to the cloud server, resulting in incomplete file data being stored. Since transferring via USB avoids cloud upload protocols, the files remain intact.
Can I recover OneDrive files that were corrupted during a Mac sync?
Yes. If you have a Microsoft 365 subscription or a work/school account, you can log into OneDrive online and use the 'Restore your OneDrive' feature to roll back your entire drive to a previous date before the corruption occurred.
Are certain Mac file types unsupported by OneDrive?
While most standard files are supported, Mac-specific package files (like iMovie libraries or Keynote presentations) are sometimes treated as complex folders by non-Mac systems. Syncing these through OneDrive can cause them to break or appear corrupted to Windows users. It is best to compress these files into a ZIP archive before uploading.
