Remove white box outline - how

[Martin ©¿©¬]

Hi
I've been sent a nice slide that I would like to use on my desktop
The slide has a white box outline line all round the slide about 10mm
in from the edges.

Anyone know know to remove this please?

It's is possible the shape has had a white line defined for it. Right click
over the line to select the shape and go to format> shape (or picture or text
box) and go to line. See if there is a defined line color and if so, choose
no line.

Thank you cayce
Tried your suggestion, but there were no options to change the text
box or line settings as none had been set
The only thing I could do was crop
