A RBAC role assignee can unexpectedly run the Add-ADPermission command on an Exchange Server 2010 server that is outside the role assignment scope

Applies to: Exchange Server 2010

Symptoms


Consider the following scenario:
  • In a Microsoft Exchange Server 2010 environment, you create a scoped management role assignment which assigns the Active Directory Permissions or Mail Recipients roles.
  • You assign the role assignment to a role assignee.
  • The role assignee tries to run the Add-ADPermission command against a mailbox that is outside of the role assignment scope.
In this scenario, the role assignee can unexpectedly run the Add-ADPermission command against the out of scope mailbox. 

Cause
