I wanted to be able to reset password in Exchange Admin Center (EAC).
When I trying to add Reset Password role for Organization Management, I encountered error message:
You don’t have access to create, change, or remove the “Reset Password-Organization Management” management role assignment. You must be assigned a delegating role assignment to the management role or its parent in the hierarchy without a scope restriction.
Login to EAC, I was able to add Reset Password role for Organization Management.
