You may change all properties of an appointment if you are the creator or manager of the appointment:

• Select   Change  and click on the option requested or
• select   Change    Appointment  to change all properties of an appointment.
• If the appointment has participants associated, BSCW will help you to inform these participants by email about your modifications and to ask them again to confirm or decline their participation.

If you change date and/or time of an appointment with participants, you should set the status to ‘tentative’ since it has to be decided again who will attend and who will not.
