Mail forwarding 'Not Confirmed'

Mail forwarding 'Not Confirmed'

Hi there,
 
I have 4 users set up on my account and I have mail forwarding to another email address for all of the 4 email addresses. But each of them states 'Not Confirmed' beside them.
 
I sent through some test emails and the emails are not being forwarded onto the designated account. Can you please look at this?
 
Thank you,
Evelyn
