That's not an error...it's just a warning telling you that it will ignore - server parameter as it is running using the Exchange Management Powershell which is what you should be using.

To ensure that the permissions have applied correctly check the user's mailboxes permissions and ensure that VSA has full permissions. You may need to wait for replication to take affect or you can restart the information store service to speed it up (if you can do it during working hours).

Hope that helps.

Hi CTEV,

Sorry i wasn't clear on what we are after. We only want to apply the permissions on one server, which is why we want to use the -server parameter

It does indeed set the permissions, but across the entire organisation while we only want to limit to one server. This particular server is in another region and we want to lock it down so other admins won't be able to have higher permissions than they require
