Question details
Microsoft Publisher displays a persistent security warning when opening a linked Excel workbook, and selecting 'Enable' fails to restore the link or provide update options.
- Product
- Microsoft Publisher
- Device & OS
- not provided
- Scenario
- Opening a Publisher document containing linked data from an Excel workbook that is stored in the exact same folder.
- Observed behavior
- A security warning appears. Clicking 'Enable' does not restore the data link or display any options to update the linked Excel file.
Verify that both your Publisher document and the linked Excel workbook are saved in the same local directory before adjusting your Trust Center settings.
Add the File Folder to Office Trusted Locations
Configuring the folder containing your Publisher and Excel files as a Trusted Location in the Office Trust Center prevents security blocks on linked data.
Microsoft Office's security policies may block active content and external links by default to protect your computer. Adding the specific folder where your files reside to the Trusted Locations list tells Publisher that the files are safe to interact with.
Launch Microsoft Publisher, click on 'File' in the top-left corner, and select 'Options' at the bottom of the menu.
In the Publisher Options window, select 'Trust Center' from the left-hand navigation pane, then click the 'Trust Center Settings' button.
Click 'Trusted Locations' on the left, then click 'Add new location' at the bottom of the window.
Click 'Browse' to locate the folder containing your Publisher and linked Excel files. Check the box for 'Subfolders of this location are also trusted' if necessary, and click 'OK' to save.
Close Microsoft Publisher completely, reopen your Publisher document, and verify that the linked Excel data updates without the security warning.
Add the Document Creator as a Trusted Publisher
If the linked Excel file or Publisher document includes a digital signature, adding the creator to your Trusted Publishers list can bypass the security warning.

Frequently Asked Questions
Why do I get a security warning even when clicking 'Enable' in Publisher?
Microsoft Office blocks linked external content from updating if the file location or publisher isn't explicitly trusted in the Trust Center. Simply clicking 'Enable' on the initial prompt may not override deeper network or folder-level security policies.
What are Trusted Locations in Microsoft Office?
Trusted Locations are specific folders on your computer or network that you have designated as safe. Any files opened from these directories automatically bypass active content security checks and warnings.
Are Trusted Documents different from Trusted Locations?
Yes. A Trusted Document is a single, specific file you have explicitly chosen to trust. A Trusted Location applies blanket trust to all files stored within a specified folder, saving you from approving files individually.
