Exports package parts of a case (evidence, chats, reports, notes, spreadsheets) into a downloadable bundle you can share with authorized people outside the day-to-day case team.
Many workflows give you a link and a separate passphrase. Share them through different channels (for example link by secure email, passphrase by phone) so one stolen message does not expose everything.
You may be able to extend expiry or rotate a passphrase without rebuilding the whole export. Ask your admin if that is enabled.
Exports can contain CJI or privileged material. Only include what the recipient is cleared to have, and log handoffs per your SOP.
