[rt-users] Error when adding user to RT 4 (email exists)

[window camera]

Hello All

I've tried to add a person in our RT, but it says "email already in use", and doesn't let me create the new user.I query everything I can find, but nothing comes up. 

Obviously this is a user who doesn't have an account yet, but was included in one of the ticket emails. However, I'm unclear how to run a query for a "non privileged" user. (And the RT Essentials book doesn't reveal how because it's for a much older version).

Any ideas how I might resolve this issue?

Thank you!

Rick
