Re: How do I set inside & outside margins in Acrobat X Pro?

With InDesign you can use a script to place the entire pdf into a document and accomodate the offset.

ID ships will a script pre-installed to place all the pages of a pdf, but to offset your's you would need to use another script located

here

install/place the script into your ID User scripts folder. (Open the ID scripts panel. Right click the User script folder and choose Reveal in Explorer/Finder)

Create an InDesign document with Facing Pages selected ((to allow shift away from the spine. (It only needs to be a single page at this point))

Run the MultiPageImporter script

In the options select Positioning Options > Reletive to Spine    Offset X: by .5

Export pdf from ID.
