Show all tickets to an unprov user that they are cc and admincc on?

I’m sure this has been asked before, but I haven’t found a specif answer
for 3.0.4:

Can RT be configured to show all open tickets to an unpriviledged web
user that they are referenced on by cc: or admincc:?

The situation is an IT manager at a client site, who is admincc: on the
queue would like to be able to see a list of all open tickets for his
organization.

Thanks in advance for your help,
Daryl
