Remarks
In order to receive this message again in the future, you will need to save the SequenceNumber and receive it using ReceiveDeferredMessageAsync(Int64, CancellationToken). Deferring messages does not impact message's expiration, meaning that deferred messages can still expire. This operation can only be performed on messages that were received by this receiver.
