Hello,
Currently I'm configurating a 2013 Microsoft Exchange server (multi-tenancy.)
The problem I'm encountering is that my tenant-administrators can view other tenant users.
Is there any way to disable the ability for tenant administrators to view the other tenants?
User1@tenant1.local
Admin1@tenant1.local
User1@tenant2.local
Admin1@tenant2.local
Both admins can view the other E-mail addresses in the ECP. How to disable this ability?
