Can’t open Office files

Lukas BeranLukas Beran

After Office or Windows upgrade, or after some change in your network, you might see an error “The file is corrupt and cannot be opened”.

This error appears when you open a file from network location, but can also appear when you open a file from your local computer if the files were downloaded from the Internet or some network share. But the solution, fortunately, is really simple:

  1. Open Office application which has the problem, for example Microsoft Word.
  2. Choose File – Options.
  3. In the left menu choose Trust Center and click the button Trust Center Settings.
  4. In the left menu Protected View uncheck all options from Protected View.

Optionally apply this approach to all Office application with the same problem.

My primary focus is the security of identities, devices and data in the cloud using Microsoft services, technologies and tools.
