Hi Folks! I have a question about opening Office attachments in Outlook that are coming up in Protected View sometimes, and regular view other times. I have users who open some Ofice attachments in Outlook in Protected view but others are opening in regular view. Things are configured to default when it comes to the Protected View settings in the Office applications meaning in Trust Center<Protected View all the checkboxes are checked for the applications. Shouldn't this mean all Office attachments are opened in protected view? Can someone explain why others are not? This is occurring in a mix of Office 2007, 2010, and 2013. Thanks!
