QUESTION: I can't paste anything into Outlook, but I can into Word, etc.
ANSWER: Open Microsoft Word, go to TOOLS> OPTIONS> Select the SAVE tab and uncheck Embed smart tags.
Also, there's a security feature in Outlook that, in certain situations requires that you have a New Mail window open first, THEN paste into. In other words, you can't copy something from another program THEN open a New Mail window. The New Mail window has to already be open.
