How can I read Exchange emails via OWA from the command line for penetration testing?

You can achieve this by writing a Python script that mimics the OWA web interface through HTTP requests. The process involves authenticating with a plaintext password, using the returned session cookie (including X-OWA-CANARY) to send JSON payloads to specific OWA endpoints like `FindItem` and `GetConversationItems`. This approach is detailed in the article Penetration Basics - Command Line Implementation for Reading Exchange Emails via Outlook Web Access (OWA), which also provides open‑source code on GitHub.
