How To Put A Border Around A Page In Word For Mac

Do not have the export email function in outlook for mac 15.9. Unfortunately, none of your suggestions apply to my file. None of the tables are joined, there are no manual page breaks, and I have set text wrapping to 'none'. Also, the repeat header functionality works fine, as long as I'm applying it to a single table in the document. It only malfunctions when I try to apply it to a 'Table Style'.
