Fix Excel Permissions Errors Caused by Broken Workbook Links
Question details
Users are encountering permissions errors in Excel because the workbook contains broken external links to local files or SharePoint directories.

- Product
- Microsoft Excel
- Device & OS
- not provided
- Scenario
- Opening or working on an Excel workbook that contains external links, particularly after files have been migrated to SharePoint Online or after a worksheet containing external data has been deleted.
- Observed behavior
- Excel displays a permissions error message attempting to access external data. This occurs because the links are broken or inaccessible, and the error persists even if the worksheet that originally contained the links was deleted.
Before modifying or breaking external connections, save a backup copy of your workbook. Breaking links will permanently convert any formulas relying on external data into static values.
Identify and Break Broken External Links
Use the built-in Edit Links tool to locate inaccessible SharePoint or local files and manually remove their connections from your workbook.
When files are moved to SharePoint or deleted, Excel does not automatically sever the external references. Even deleting the specific worksheet containing the link may leave the connection active in the background, triggering permissions errors.
Navigate to the Data tab on the Excel ribbon and click on Edit Links (or Workbook Links in newer versions) located in the Queries & Connections group.
In the dialog box, select the external sources listed and click the Check Status button to identify which links are broken, unverified, or inaccessible.
Highlight the broken SharePoint or local link causing the permissions error and click Break Link. Click Break Links again to confirm the prompt.

Remove Hidden External Links in Name Manager
If the permissions error persists after checking the Edit Links dialog, the broken link may be hidden inside named ranges.

Frequently Asked Questions
Why do I still get permissions errors after deleting the worksheet with external links?
Deleting a worksheet in Excel does not always remove the workbook links associated with it. The reference may remain cached in the background within the 'Workbook Links' or 'Edit Links' dialog, requiring you to break the link manually to stop the permissions error.
Will breaking an external link delete my spreadsheet data?
No, breaking a link will not delete your data. However, it will permanently convert any formulas that relied on the external workbook into static text or numbers, meaning those specific cells will no longer update automatically if the source file changes.
How do I know which external link is causing the permissions error?
Go to the Data tab and click 'Edit Links'. Highlight the links in the list and click 'Check Status'. Links returning an 'Error', 'Unknown', or 'Source not found' status are typically the ones triggering your permissions issues.
