[FIX] The File Couldn’t Open in Protected View

Protected View is a security layer provided by Microsoft. It is a read-only mode in which most editing functions are disabled. Additionally, Protected View is enabled by default. Moreover, this is useful when opening files from unknown locations on your computer, the Internet, or through Microsoft Outlook.

Although this mode is enabled for security purposes, there are reports from users that Protected View also causes issues. Users have said that opening files either shows that they are corrupt or they remain stuck on the opening screen. This issue occurs when opening either a Microsoft Word or Excel document. Also, the files causing issues are mostly downloaded from Microsoft Outlook.

The file couldn’t open in Protected View

The solutions and workarounds provided here have been taken from reliable sources. Hence, the solutions are from users as well as Microsoft Insiders.

Disable Protected View

The first solution is to disable Protected View settings. This is a very common workaround for files secured by Information Rights Management (IRM) not opening in Protected View. IRM embeds the user permissions and encryptions directly into the file as it may contain sensitive data. This issue occurs mostly when opening Excel files. However, this solution can be applied to other Microsoft Office applications as well. To disable Protected View

  1. First, open MS Excel or MS Word.
  2. Second, click on Options in the bottom-left corner.
    Click on Options
  3. Click on Trust Center. Then, click on Trust Center Settings.
    Click Trust Center Settings
  4. Under Protected View make sure that all options are unchecked.
    All options unchecked
  5. Then, click on OK and then OK.

Again, remember this is only a workaround and only recommended when opening the file is important. Consequently, only try this method if you have a strong antivirus installed.

Resetting Trust Center Settings

This solution was provided in the case of a Windows update or Office 365 update causing changes in the Trust Center Settings. Microsoft is known for pushing updates that change the settings of certain apps as a direct effect or indirectly. Therefore, you will have to manually reset your Trust Center Settings to default. By default, Protected View is enabled. To reset your settings

  1. First, open MS Excel or MS Word.
  2. Second, click on Options in the bottom-left corner.
