Hi Radek, I think we can do this in Dutch as well ;-)
Do you mean hang as in you have to close Outlook or hang as in; it has to
think about it for a few seconds before continuing?
Does the same issue occur when you paste in Outlook Safe Mode?
What are you pasting it into? E-mail message? What operating system? How
much RAM do you have in the machine? Have you let it sit for a very long
time to see if it ever comes back? What antivirus software are you using?
I had pasting problem in Office 2010. Made search in Google, there was hard to find an answer also, but at last I figured it out.
In the first forum that I found I wasn't able to register. This is second and I post a solution here.
In Office 2010: New E-Mail -- File -- Options -- Mail -- Editor Options (Compose Message) -- Advanced -- Cut, copy, and paste - Pasting from other programs -- Keep Text Only -- OK
