How can the Session mechanism in requests_ntlm improve efficiency in EWS interactions?

By using `requests.Session()` with `HttpNtlmAuth`, the Session mechanism reuses authentication credentials across multiple requests, reducing the number of NTLM handshakes. This shortens communication packets and improves performance, especially when performing bulk operations like email downloading. The article demonstrates switching to a session-based approach to streamline automated tasks in EWS development.
