[SOLVED] Sending a room-bound event via ews

Sending a room-bound event via ews

I send an event using https://learn.microsoft.com/en-us/exchange/client-developer/exchange-web-services/how-to-create-appointments-and-meetings-by-using-ews-in-exchange-2013

The event is created, only for participants. No event is generated in the room. How do I send an event to a room?

Solution

You need to use the resource element https://learn.microsoft.com/en-us/exchange/client-developer/web-service-reference/resources and include your Room as an attendee eg

</t:OptionalAttendees>
<t:Resources>
  <t:Attendee>
    <t:Mailbox>
      <t:Name>Resource1</t:Name>
      <t:EmailAddress>resource1@contoso.com</t:EmailAddress>
      <t:RoutingType>SMTP</t:RoutingType>
      <t:MailboxType>Mailbox</t:MailboxType>
    </t:Mailbox>
    <t:ResponseType>Unknown</t:ResponseType>
  </t:Attendee>
</t:Resources>
</t:CalendarItem>
