Creating a transport rule manually
You must manually create the transport rule for Exchange Server 2010
SP2. With Exchange Server 2013 or later you can have the connector
create the transport rule for you, or create it yourself.
Manually creating a transport rule in Exchange Server is a two-step
process in the Exchange Management Shell program, in which you
create the foreign connector and then the transport rule.
To create a foreign connector
If faxes will be sent from Office 365, do not create a foreign connector.
