Take care when sending Microsoft Office files to outsiders, you might send hidden confidential data with it.
  • The presenter notes fields in PowerPoint might contain notes you do not want others to read
  • Taking out the data labels with confidential numbers from a data chart does not remove the actual data in the underlying spreadsheet
  • The PowerPoint sticky notes links are very small, which is great so they do not obstruct the design of the slide, on the other hand, you might just forget to remove them.
PDF-ing your document will solve most of these issues.
