Exchange Online ExchangeOnlineManagement Set-*

The Set-PendingFederatedDomain cmdlet is used by the Exchange admin center to configure pending domains with the federated organization identifier in the federation trust for the Exchange organization. You shouldn't use this cmdlet to attempt to manually configure a federation trust. The domains being added to the federation trust must exist as accepted domains in the Exchange organization.
