How to Embed PDF File in Outlook Email Body?

My outlook interface is not even this. How do I follow?

It only works for the first page. Can you do this with a multi letter document

How do I keep the PDF with links in the e-mail body?

How do I enable Adobe Acrobat Document option? I don't see it in the list of options.

Is there a similar feature on Gmail? Thanks in advance!

thanks
