Fix Excel on Mac OneDrive Links Failing When Both Files Are Online
Question details
The user encounters an error in Excel for Mac when trying to open a workbook that contains external links to another workbook stored on OneDrive.

- Product
- Microsoft Excel, OneDrive
- Device & OS
- macOS
- Scenario
- Opening interconnected Excel workbooks directly from OneDrive on a Mac.
- Observed behavior
- Excel displays an error and fails to update links when both files are stored online in OneDrive. The error does not occur if the linked files are opened locally.
Ensure your Mac has a stable internet connection and verify that the OneDrive sync client is actively running in your menu bar with no pending sync tasks.
Verify File Synchronization and Update Software
Ensuring that your files are fully synced and all related software is up to date can resolve underlying bugs causing link failures.
Software updates often contain essential bug fixes for cloud synchronization and external link management between Microsoft Excel and OneDrive.
Click the OneDrive cloud icon in the macOS menu bar and confirm it says 'Your files are synced'. If it is currently syncing, wait for it to finish.
Open Excel, go to the 'Help' menu at the top, and select 'Check for Updates' to launch Microsoft AutoUpdate. Install any available Excel updates.
Open 'System Settings' (or System Preferences), navigate to 'General', and click 'Software Update' to ensure your operating system is current.

Use Local Copies as a Workaround
Since the error only occurs when files are opened from OneDrive online, working with local copies temporarily bypasses the issue.
Report the Issue to Microsoft Support
If local workarounds are not viable, contacting Microsoft Support or the Community can help escalate this specific Mac and OneDrive bug.

Frequently Asked Questions
Why do Excel links fail when both files are stored on OneDrive?
When Excel files are stored on OneDrive, the file paths often switch to web-based URLs. Excel for Mac sometimes struggles to authenticate or resolve these online paths, causing external link errors.
Does reinstalling the OneDrive app on Mac fix external link errors in Excel?
No. According to extensive user reports, simply reinstalling the OneDrive macOS application does not resolve this specific issue, as the bug is related to how Excel processes online workbook paths rather than the sync client itself.
How can I fix the Excel OneDrive link error immediately?
The most reliable immediate workaround is to download both the main workbook and the linked workbook to your Mac's local storage. Once downloaded, update the external links in Excel's 'Data' tab to point to these local files.
