Question

How can I export our tickets including all the ticket details such as comments or email addresses?

Answer

Based on the type of account you have, there are different options to perform a full-ticket data export:

If you subscribed to a Suite Growth or Professional Support plan or higher, and you are an administrator with access to native export options, you can perform a JSON or full XML export. For more information, see the article: Exporting data to a JSON, CSV, or XML file.
For accounts on any plan, utilize the API. To export tickets in bulk, use the API end-point of the incremental ticket events with comment_events in side-load.
