I consulted Microsoft Accessibility and my problem was not solved. I am using the most current versions of Office 365 and Windows 10 Home.
I used to be able to remove Protected View from a given document using the context menu in Windows Explorer and going into the file properties. Alternatively, I could open the file and go under File then Info. I am not finding this option in either place.
I do not want to remove Protected View for all documents I receive.
