Sometimes I have to paste a line or two of code, or a few lines of a stack trace. Sometimes I have to paste a string which contains some particular set of characters. Microsoft Lync absolutely destroys the pasted text. It subtly converts the double quotes into some unicode nonsense. Then it converts some common character sets into smilies. When you copy text from Lync it is almost always guaranteed to be different from what what entered originally. God, I hate Lync with a passion.
