A family of Microsoft word processing software products for creating web, email, and print documents.
With Word's default settings it is normal that files from certain sources (and files of certain types) open in Protected view. Or are you saying that the file(s) won't open at all?
You can turn off the options at File | Options | Trust Center | Trust Center Settings | Protected View if you wish. Be careful when opening potentially unsafe files.
First of all, see if turning off Read Mode makes a difference. At File | Options | General, clear the check mark next to "Open e-mail attachments and other uneditable files in reading view." Read Mode is not a security setting, and usualy you just want to start editing a document immediately of course.
