Do this. Pickup any office document ( Word , Excel, Powerpoint ) which was sent across to you & have a look at the properties.

 

Bet  you could be amazed with the details you find.

In some documents I received I found details of persons who originally wrote the document, over a period of time it was changed hands & the new author simply edited it & sent it across as his or her own work.

 

Solution ?

Cleanup the properties before sending the file across.

Office 2007 & 2010 have a built-in feature which can be found under

File>Info>Check for Issues > Inspect Document.

 

And oh ! This is not a new Feature.

 

For office 2003 / 2002 ( XP ), you have to download & use an add-on.
