Error message in Office when a file is blocked by registry policy settings

A file is blocked when you open or save the file in a Microsoft Office program. In this situation, you may receive an error message that resembles one of the following:

  • You are attempting to open a file that is blocked by your registry policy setting.

  • You are attempting to open a file type <File Type> that has been blocked by your File Block settings in the Trust Center.

  • You are attempting to open a file that was created in an earlier version of Microsoft Office. This file type is blocked from opening in this version by your registry policy setting.

  • You are attempting to save a file that is blocked by your registry policy setting.

  • You are attempting to save a file type that has been blocked by your File Block settings in the Trust Center.

Resolution

To resolve this issue, try the following general resolutions to change the File Block settings to disable the restriction of certain file types:

  1. Select File > Options.

    If you cannot open a file in Office, open a blank document to start the Office application. For example, if you cannot open a Word file, open a new document in Word 2019 or Word 2016 to see the option.

  2. In the Options window, select Trust Center > Trust Center Settings.

  3. In the Trust Center window, select File Block Settings, and then clear the "Open" or "Save" check box for the file type that you want to open or save.

    Note

    Clear the option means allow user to open or save the file. Check the option means block the file.

    Trust Center window

  4. Select **OK **two times.

  5. Try to open or save the file that was blocked again.

The issue can also occur when you open an embedded or linked Office file in an Office application. For example, you have a Visio object embedded in a Word document. When you try to open the Visio object, you receive a similar error message in Word. To resolve this issue, you must change the File Block settings in the application that owns the blocked file type. In this example, you must change the File Block settings in Visio instead of in Word. If the error message mentions Excel file type, go to Excel to change the File Block settings.
