Editing the 'CC' or 'to' on emails

[Duncan.F]

Hi,
I got an email with a large number of addressess on whom I would like to 'reply to all'. However, when I go to send the email I get an error message which says there is an error with some of the email addresses. How can I edit these out please?!

Ta,

Dunc
