I understand this request as the feature in Outlook: you receive an email, and you can create an event in the calendar. It doesn't need to be a meeting request or anything. I used it a lot at work, where we use Outlook, simply to block time to perform a task. Creating the event from the email is very convenient as sometimes they come with a link, or an attachment, or you know you'll do it like it two months and you wont' find the email.
