Macintosh and PDF Portfolios

We have one user who is on a MAC. He is running Outlook (exchange) version 14.6.7. He needs to be able to create PDF portfolios from his email. Is that possible using Acrobat? Also, we are licensed for Acrobat XI for windows. Will our serial number work for the Macintosh or do we need to buy a whole new license?

Is Acrobat XI compatible with his version of Outlook? He is running the most recent MACOS.
