I have a PowerPoint file created in Microsoft Office 365 (2013) and we password protected it. The only thing I'm trying to delete now, but it still shows the password. It shows 2 levels of password, if I encrypt it, it shows it, but then again asks for a "reserved" password. Then I can remove the "encrypt" password, but it still has a "reserved" password. Does anyone know how to remove a “reserved” password? I can't seem to find anything on the Internet.
