You used to be able to copy contents of the sent email history and paste it in another application, for some reason the copy and paste isn't working in the sent email history.? Would it be possible to re-enable it.?
Do you mean from the viewer after clicking View?
In the records tab, click email, then email history then find the email you want and click view on the right to see the email sent. shows you the email that was actually sent. You used to be able to copy the email text, but it seems to be disabled now.?
