Archive Explorer - I can see more archives than I should be able to

I have discovered I can see things in Archive Explorer I don't believe I should have permission too

It's random as well - see screen shot below. Some archives I can open and see all sub folders and all emails. Some just calendar, or Restored folders...like I say random.

I'm logged in as a test user, check Credential Manager has cached any passwords. It's not impersonating the EV account. I've looked at the following Technote:

Check this is configured - it is

Ev is 10.0.2.1112

Any ideas what I can look next?

check it out. I can see everything of Lawrence. Certain things of Nicky and Christian. Nothing of Malcolm, Anant and Louise??
