Powerpoint

Hi Clare

Thanks for getting in touch. I wanted to check the process you're following for this first:

Go to View > Slide Master.

Assuming you wish to change every slide in the presentation, select the top-most slide in this list on the left.

On the Slide Master menu, go to Slide Orientation > Portrait / Landscape as desired.

Close the Slide Master and this should change all slides in the presentation (assuming there's only one Slide Master in the presentation.

Does this help?

Kind regards
