The scenario I am looking here may need some customization but here is the question.
Whenever an entry or record is added to sharepoint calendar, I would like the same event (or appointment) to appear in their email client (Such as outlook, lotus etc).
Currently I am able to send out to the email client but the user has to open it and accept it. We would like it to be added directly to the users calendar in their email client (outlook, lotus etc).
