New Transport Rule to BCC all outbound & inbound emails for one user - Exchange 2010 Hsoted More

Client has a new intern and they want to BCC the manager for this intern on all incoming and outgoing emails.

Exchange 2010 Hosted Mode so power shell only.

Managed to setup the outbound rule:
new-transportrule -Name 4950BCCMRoutbound -From admin@domain -BlindCopyTo manager@domin.com
That gives confirmation

But how do I setup the inbound rule? Tried:
new-transportrule -Name 4950BCCMRoutbound -To admin@domain -BlindCopyTo manager@domin.com
but that results in the error:
A positional parameter cannot be found that accepts argument '-To'.
    + CategoryInfo          : InvalidArgument: (:) [New-TransportRule], ParameterBindingException
    + FullyQualifiedErrorId : PositionalParameterNotFound,New-TransportRule

Any help please
Thanks
