There's nothing special in PDF about a watermark - it's just some of the text or graphics. So it will be exported with everything else.
Why do you mention Skype?
I mention Skype because all the microsoft help items say to uninstall Skype click-to-connect and then tables will paste from adobe pdf into word documents and retain complete table. I was able to copy the pdf document to the clipboard and then paste it into the word document and have it retain the table, rather than just list as text. But when I do the copy and paste this way, I get the watermark from the pdf, which I don't want.
If these Microsoft help items are on the web, can you give use the address (what you see at the top of the page starting http)? That will make sure we are on the same wavelength as you. I've never encounted any of these issues.
