How can I paste text without format in Lync's chat window?
Solution 1:
You can use ctrl-alt-v to paste without formatting.
Solution 2:
Copy and paste it to notepad or another plain text editor.
Copy it from notepad into your target application, Lync in this case.
Solution 3:
You can use PureText or other similar utilities. I use it and it works with Lync flawlessly. By default it allows to convert'n'paste text by pressing Win+V, but seems like it can override Ctrl+V too.
Solution 4:
I use ClipX as a clipboard tool, and when I paste from its menu (Win+Insert) it pastes plain text.
