When working in Apple Mail, you can use Daylite Mail Assistant to create Appointments in Daylite or link emails to existing Appointments. This helps you to make sure you don't double book your time. This also ensures you have all the necessary information linked to the Appointment.
To the right of your email in Mail is your Daylite Mail Assistant window. Here you can either select the Link icon; to link the email to an existing Appointment, or click the "+" sign, to create a new Appointment.
For a new Appointment, create a name, schedule the time, and add any important details.
To edit a linked appointment, click the arrow to the right of the highlighted linked appointment and then select "Edit".
Be sure to click "Save" once you've entered all the necessary details.
