Question details

The user needs to unblock a Microsoft Access (ACCDB) file located on a network share in another domain after standard trusted location methods failed.

How to Unblock a Microsoft Access File on a Network Share

Product: Microsoft Access
Device & OS: not provided
Scenario: Opening an ACCDB database file stored on a network share located in a different domain.
Observed behavior: Microsoft Access displays a 'The file content is blocked' error message, and adding the domain to Trusted Sites and Trusted Locations does not resolve the issue.

Before you start

Ensure you have the correct network path for the shared folder (e.g., server/share) and that you have administrative privileges to modify your system's Internet Options.

Solution 1Recommended

Add the Network Share to Internet Options using the File Protocol

Resolve the blocked content error by adding the exact network share path to your trusted sites using the specific file:// URL format.

When an Access file is stored on a network share across domains, standard HTTP URL formats may not properly register in Internet Options as a trusted location. Using the correct file URL format bridges this gap.

Open Internet Options

Search for 'Internet Options' in the Windows Start menu and open the control panel application.

Navigate to the Security Tab

Click on the 'Security' tab at the top of the Internet Properties window, select 'Local intranet' or 'Trusted sites', and click the 'Sites' button.

Enter the Network URL

In the 'Add this website to the zone' field, type the location using the file URL format, such as file://server/share (replacing server and share with your actual network path), and click 'Add'.

Save and Restart

Click 'Close' and 'OK' to save your changes, then restart Microsoft Access and open the ACCDB file.

Add the Network Share to Internet Options using the File Protocol

Bypassing Internet Macro Blocks: Properly formatting the network path as a file:// URL aligns with Microsoft's strict security policies, effectively bypassing the internet macro block default behavior.

Frequently Asked Questions

Why does Microsoft Access say the file content is blocked on a network share?

This happens due to a Microsoft Office security feature designed to block macros and active content originating from the internet or untrusted network domains. If your network share is not explicitly recognized using the correct protocol, Access blocks the file to protect your computer.

How do I correctly format a network path for Internet Options?

When adding a network share to Trusted Sites or the Local Intranet zone, you must use the file protocol format instead of a standard web address. For example, instead of typing '\\server\share', you should enter 'file://server/share'.

Can I use WPS Office to open Microsoft Access ACCDB files?

No, WPS Office is an excellent alternative for Word processing, Excel spreadsheets, PowerPoint presentations, and PDFs, but it does not include a relational database management system to natively open or edit Microsoft Access ACCDB or MDB files.
