Colourspace for PDF

I have a pdf that has been exported from PowerPoint. The pdf is intended for screen viewing only. So all the colours in the ppt were set up as RGB. When I open the pdf in Acrobat, what I see looks like it's viewing the RGB document in CYMK. It's dull, obviously many RGB colours don't reproduce in CMYK. The only way I can see the pdf as intended, is if I go to print production > output preview > and choose the simulation RGB  profile. Is there a way that I can make acrobat open, that particular pdf automatically with RGB profile? And will it open it in RGB on other users versions of Acrobat?

Your document is converted from RGB to CMYK: it looks like a conversion settings issue.

I don't believe that's the case. If I'm in Output Preview and I choose "show" "CYMK" notthing in the document shows up, but when I choose "show" "RGB" all the elements are there.

I did follow a few other threads and found a tip that in my Acrobat preferences if I have "Use Overprint Preview" set to "Always" it displays in the dull way that looks like the CMYK conversion (I'm not saying that's what is actually happening, but it's how I would explain the colour difference), but if I set it to "Never, " the document colours show up as intended.

I do think it must be the way PPT is exporting the pdf, as I also have the same file built in Indesign and if I export a RGB pdf from there the colours look as intended, no matter what my preferences overprint preview setting is.
