Compartilhamento de arquivos - bloqueio

Hello, how are you?

Thank you for contacting the Microsoft Community.

My name is Patrício, I am an independent advisor and I will do my best to help.

A file is blocked when you open or save it in a Microsoft Office program. In this situation, an error message similar to the following is displayed:

You are trying to open a file type that is blocked by the registry policy setting.

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

You are trying to open a file that was created in an earlier version of Microsoft Office. This type of file has been blocked by the registry policy setting and cannot be opened in this version.

You are trying to save a file type that is blocked by the registry policy setting.

You are trying to save a <File Type> file type that has been blocked by the Advanced File Block settings in the Trust Center.

Resolution

To resolve this issue, try the following general resolutions to change the Advanced File Lock settings to disable restriction on certain types of files:

Select File> Options.

If you are unable to open a file in Office, open a blank document to start the Office application. For example, if you are unable to open a Word file, open a new document in Word 2019 or Word 2016 to see the option.

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

In the Trust Center window, select Advanced File Block Settings and clear the "Open" or "Save" checkbox for the type of file you want to open or save.

Observation

Deselecting the option allows the user to open or save the file. Checking the option means locking the file.

Trust Center window

Select OK twice.

Try to open or save the locked file again.

Observation

File Lock Settings can be controlled by a Group Policy Object (GPO) and are part of the recommended security baseline settings. Enabling a file type that is blocked by default can compromise security.

Here's how to open the GPO:

Open the Group Policy Management Console.

Navigate to the following GPO:

User Configuration \ Administrative Templates \ Microsoft <Product Name> \ <Product Name> Options \ Security \ Trust Center \ File Block Settings

Replace <Product Name> with the name of the affected Office application, for example, Word 2019.

You may also have to download Administrative Template files to use the GPO.

More information

The problem 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 has the file type blocked. In this example, you must change the Visio File Lock settings instead of Word. If the error message mentions an Excel file type, go to Excel to change the File Block settings.

If there are more questions regarding Microsoft products or the reported behavior persists, please post again.

I hope I helped, see you later!
