Hello Dileep Uvaraj (INFOSYS LIMITED),
Thank you for reaching out to Microsoft Support!
According to the documentation, when we use the Graph API to create an event, the request body is an event object, the object does not have the attributes of BCC and CC, but the attendees attribute is a set, you can send the user you need to fill in the set.
For disabled forwarding can refer to the case, using extended attributes. This is a solution shared by other users, but it does not always work, you can try it.
Hope this helps.
