Hi see:

Required Permissions:
Please make sure that the account used is a member of the Local Administrator
group. This should be fulfilled on Exchange servers by being a member of the Organization Management
group. However, if the group membership was adjusted or in case the script is executed on a non-Exchange system like a management server, you need to add your account to the Local Administrator
group. You also need to be a member of the following groups:
- Organization Management
- Domain Admins (only necessary for the
DCCoreRatio
parameter)
