Use only media types accepted by the module allowlist, including supported image, audio, video, PDF, text and office-document formats.
Open guide →GuideUnderstand secure attachment storage
Know that stored media uses randomised names and is served through an authorised controller rather than a public guessed path.

Open the message and select its media link; the controller checks account View access, path containment and file existence.

Know that protected downloads send a safe filename, Content-Disposition and X-Content-Type-Options: nosniff.

Confirm the message has a media path, the file remains inside the managed upload directory and the current staff can view the account.

Understand that a conversation request returns a bounded page to protect the browser and server.
