# Known Limitations

Panopticon decrypts most RMS encrypted documents, with the following known limitations:

- Text is decrypted from RMS protected PDFs, but not text formatting, images or subfiles.

- Email clients such as Microsoft Outlook can protect email messages as rights-managed email messages. In these cases, it stores the contents of the original message as an encrypted rpmsg attachment. Panopticon does not support decryption of these encrypted attachments.
