RBAC in Exchange 2010

Can anyone assist with the below EMS error I recieve trying to add a role assignment with an OU scope:

WARNING: The domain.com/Group Objects/Stellar management scope won't be applied to the management role assignment for the Stellar DistributionGroups Management management role because the implicit scope on this role, MyDistributionGroups, is smaller than the specified scope.

I'm using a custom role named StellarDistributionGroups Management with the following entries (parent is distribution groups):

I'm running the following cmdlets:
[PS] C:\>New-ManagementRoleAssignment -Name "Stellar DL Managers" -SecurityGroup "stellar Distribution Group Managers" -Role "Stellar DistributionGroups Management" -RecipientOrganizationalUnitScope "domain.com/Group Objects/SA"
LVL 19

there is a conflict in scope which you are specifying. try setting the same scope as StellarDistributionGroups mgmt role.

i wonder why myDstributionGroups some into play.

how do you create your management role?

the right way is to use
new-managementrole -parent "Distribution groups" -name "StellarDL"

then run to find out what command you have
get-managementrole "StellarDl" | get-managementroleentry

if you want to remove command you basically do
get-managementrole "StellarDl" | get-managementroleentry <command you want to remove> | remove-managementroleentry -confirm:$false

then you run the below command
New-ManagementRoleAssignment -Name "Stellar DL Managers" -SecurityGroup "stellar Distribution Group Managers" -Role "StellarDl" -RecipientOrganizationalUnitScope "domain.com/Group Objects/SA"
p/s: you need to create the security group "Stellar distribution group managers" manually before run the command


New-RoleGroup -Name <role group name> "Stellar DL Managers" -Roles <roles to assign> "StellarDl" -RecipientOrganizationalUnitScope "domain.com/Group Objects/SA"

p/s: remove the <comment> .. the above way will create the group in

please be very specific where you stuck so i can assist you further.
