I'm getting an error while trying to play a message using admin credentials. The admin used for authentication has mailbox delegate role. I am able to connect to the specified extension successfully but not able to play the message on the specified extension.  Below is the request sent to server and the error received. if I use the user credentials and send the request mentioned below it works fine but I need this to work with admin user that has Mailbox delegate role.

Thanks Utkarsh! That worked. It'll be very helpful to others if this info is updated in your CUTI docs. We knew that it needs userobjectid but didn't know where to pass this info.
