Exchange 2010 RBAC Manager (aka RBAC Editor GUI) - updated on 8/14/2010

RBAC Manager puts all efforts to simplify the RBAC administration. Basically it provides the missing GUI to edit RBAC settings on Exchange 2010 systems; including adding/removing cmdlets, cmdlet properties, assignments etc. RBAC tool is written in C# and using Powershell behind the scenes
Pre-Requirement: You need to have Exchange 2010 Management Tools installed prior to running RBAC GUI
