RBAC Manager R2
RBAC Manager R2 is a great tool posted on CodePlex that really helps with RBAC (role-based access control) administration. For anyone who has truly drilled down into role groups and roles and looked at (and managed) the underlying PowerShell code that goes with each one, you know how difficult it can be to go through the Exchange Management Shell. RBAC Manager offers a GUI-based approach that makes the process much easier. Through the tool, you can add or remove cmdlets, alter cmdlet parameters, and more.
