It seems that a Word document that contains some text that looks like an email address (e.g., firstname.lastname@example.org) but that is intentionally NOT marked as a hyperlink, is turned into a hyperlink in the resulting PDF when saving as a PDF.
How can I save a Word document (using Word 2007) as a PDF and prevent any hyperlinks to be created?
(I am pretty sure that it is a hyperlink encoded in the PDF. As when opening the PDF in Adobe Acrobat 8.0, SumatraPDF or Google Chrome, all three viewers indicate a hyperlink when hoovering over the relevant email address)
Note - again - that they are never marked or shown as a (blue, underlined) hyperlink in the Word document itself. Only in the PDF they become clickable when you hover over them.
