What happens if you are not authorized to open an RPMSG file?

If you are not an authorized recipient, you will not be able to access the contents of the RPMSG file. Microsoft Outlook or the supported viewing service will ask you to verify your identity. If your account does not have permission, the message will remain encrypted and cannot be opened. This security measure protects confidential information from unauthorized access. To gain access, you must contact the sender and request permission. Only the sender or the organization that created the protected email can change the access rights and allow additional users to view the message.
