Sent email...BCC Field

For a sent email, how can I see who was in the BCC blind copy field?

Open email in SENT folder

I tried that before I asked for help. When I sent the email, I included a group list in the bcc section, and when I used to use Outlook I could easily see the list when I opned the email in my sent folder. On this emClient…I can’t seem to be able to see the same list.
