Enabling sessions on a Service Bus queue sets the RequiresSession property on the entity. When messages are sent, assigning the same value to the SessionId property groups those messages into a single session. Service Bus delivers only one session at a time to a consumer, so a single worker processes all messages for that session sequentially, preserving order and preventing concurrent handling of the same account. Because different SessionId values can be processed on different connections, other workers can simultaneously handle messages for other accounts, providing horizontal scalability. Duplicate detection relates only to eliminating repeated messages and does not enforce ordering. Partitioned queues distribute messages across multiple partitions and make ordering nondeterministic across partitions. Dead-letter queues are for undeliverable messages and do not influence ordering or concurrency.
