Traditional Exchange Integration (Mode A)
This assumes current functionality, which involves using the Bookit plugin to create and manage bookings in Outlook. Any updates made in the web application are managed using EWS. It is now possible to use Graph API instead of EWS, but only when using Exchange Online.
Starting with Korbyt Booking version V6.6.1.0 it has been possible to enable EWS updates for the WebApp, which means that VCALS can be disabled from alerts, as we are able to use EWS to create the appointments for bookings created in the main web app.
Exchange Room Synchronization (Mode B)
This is a different mode of operation and involves mapping the Korbyt Booking rooms with a corresponding Exchange Room mailbox ID. This allows the Exchange (Outlook) user to create an appointment and book an Exchange Room directly, i.e., without needing to launch the plugin. This will automatically book the corresponding room in Korbyt Booking.
Types of Exchange Configuration / Authentication Options Available
These types for both modes of operation listed above
EWS On-premise (basic authentication only)
EWS Online with basic authentication
EWS online with OAuth
Graph API (online only)
