We are missing each other. When a client makes a booking, Admin receives an email with the booking information and an Outlook.ics file for the calendar.
When Admin opens the ICS file, the booking for the customer is added to the Outlook diary on the date and time of the booking. Even though the Client name does not appear on the Outlook ICS file, one can add the name and edit that into the heading after saving.
The notification that the employee receives also has an Outlook.ics for the appointment, however, the date of the file saving is the same day you open the file and not the time and date of the actual booking.
The date must be Tuesday 09 May 2023 10:00-11:00 not Wednesday 19 April 2023 15:03-15:03
The Staff cannot edit the file to change the date or the time and date. One cannot add the client's name at all.
Hope this guides you in the right direction.
