Solution 1Recommended

Unblock the File in Windows Properties

Use this method to remove the Mark-of-the-Web (MOTW) block that Windows applies to downloaded files.

Modern Office security policies often block macros in files downloaded from the internet, even if the source is in your Trusted Sites.

You can manually unblock individual trusted files directly from the Windows file properties.

1
Open File Properties

Right-click the downloaded Excel file on your computer and select 'Properties' from the context menu.

2
Locate Security Settings

Go to the 'General' tab and look at the bottom for a Security section.

3
Unblock the File

Check the box next to 'Unblock', click 'Apply', and then click 'OK'. When you open the file again, Excel will allow the macros to run.

Unblock the File in Windows Properties
Missing Unblock Option: If you do not see an 'Unblock' checkbox, the file is not currently blocked by the Windows MOTW security feature.

Frequently Asked Questions

Why is my Excel file blocked even though the site is trusted?

Microsoft Office uses a security feature called Mark-of-the-Web (MOTW). When a file is downloaded from the internet, Windows tags it. Modern Office versions often block macros in tagged files by default, overriding the Internet Options Trusted Sites list.

Is it safe to use the Unblock feature on downloaded Excel files?

It is safe only if you are absolutely certain the file comes from a trustworthy source and you expect it to contain macros. Unblocking a malicious file can lead to malware infections.

How do I globally enable macros in Excel?

You can change global macro settings by going to File > Options > Trust Center > Trust Center Settings > Macro Settings. However, selecting 'Enable all macros' is highly discouraged due to significant security risks.
