PowerShell: Forward email to external recipient

The solution can sometimes be to forward all inncoming email, and some times to an external or internal address.

Incase of beeing external address, we need to create a contact in our Addresslist:

New-MailContact -Name <Display Name> -ExternalEmailAddress <External Recipient Email Address>

Then we can forward email to this address:

Set-Mailbox username -DeliverToMailboxAndForward $false -ForwardingAddress address

You can choose wether to leave a copy in your inbox ($true) or delete it from the inbox when its forwarded ($false), or if you dont define it the default is saving a copy.
