Details: I have been asked to include a .xlsx file in a pdf portfolio for work. However, when I or others try to open the file, it says “Adobe Acrobat cannot open the file attachment because your administrative security settings do not allow opening file attachments”. When I try to do it as an attachment as opposed to part of the portfolio, I get the same error.

As a test it does the same thing for .docx files, so it appears to be a pretty universal problem. It obviously still works for pdf files. I am on a federal government computer, so I might be restricted there.

Any ideas how to fix or get around this?

Thank you
