The simple answer is "no," at least in 2.5.x of Clearspace. The next question is, "will Jive be providing MS Office integration in?"
For example, it should be simple to paste directly from Word or Outlook or Excel into Clearspace. Right now, it sort of works. But it doesn't work well if you need to in any way edit or modify the document you created by pasting. All the HTML garbage code that MS inserts messes up the rich text editor. So, you are better off pasting into Notepad to strip all that out, then pasting into Clearspace from Notepad.
