As requested in Ticket 447155 please find Feature Request.

Our Exchange admins would like to see some specific identifier in headers, API, subject or similar that they could use to create Exchange rules to identify bookings from Condeco platform.

e.g. allow a customisable template to be used for meetings booked through Outlook/App in which we could add "CB" (Condeco Booking) to the meeting subject.
This way we could block all other requests and thus only accept those made through Condeco
