After Azure RMS(AADRM), Can not open old protected message(by AD RMS) RRS feed

  • Question

  • Hi Experts.

    I migrated Azure RMS from On-premise AD RMS.

    New message is working but old message(by AD RMS) is not opened OWA.

    Outlook try to connect Azure RMS directly via Registry, but OWA reconize old message like external IRM Message.

    "This message is protected with Information Rights Management by an external organization and can only be opened using Outlook. Download a free trial of Microsoft Office Outlook"

    I completed all migration process (include export/import TPD).

    Outlook can decrypt old message via AADRM, but OWA don't connector to AADRM.

    Can I change this behavior?
