Create PDF Documents in Office 2010

Office 2010 includes a built-in PDF writer to help you save any document into the PDF format at the click of a button. You can also convert documents to PDF and email them as attachments directly from the Office program.
To save a document as PDF, go to Share -> Create PDF Document. Alternatively, you may use Share -> Send Using E-mail -> Send as PDF to attach a PDF copy of the document in a new email message.
Office 2007 users can download the free "Save as PDF" add-on to export files as PDF format in their Office programs.
