How to import appointments with multiple regarding attendees

Looking to import appointments from a different d365 environment. I have exported them to excel but I am unable to import the appointments with multiple attendees as the lookup field only allows 1 record.

Any ideas how this can be imported?

Step 1: Import Appointments

  1. Prepare Your Excel File: Ensure your Excel file has all the necessary fields for the appointment entity, such as Subject, Start Time, End Time, and any other required fields.
  2. Use the Data Import Wizard:
  • Navigate to Settings > Data Management > Imports.
  • Click on Import Data and select your Excel file.
  • Map the columns in your Excel file to the corresponding fields in the appointment entity.
  • Complete the import process to create the appointments in Dynamics 365.

Step 2: Prepare Attendees Data

  1. Create a Separate Excel File for Attendees: This file should include columns for the Appointment ID (or some unique identifier), Attendee ID, and any other relevant fields.
  2. Export Appointment IDs: After importing the appointments, export the list of appointments from Dynamics 365 to get their unique IDs. You can use Advanced Find or a similar tool to get this list.

Step 3: Import Attendees

  1. Link Attendees to Appointments:
  • In your attendees Excel file, ensure each row links an attendee to an appointment using the Appointment ID.
  • Navigate to Settings > Data Management > Imports again.
  • Click on Import Data and select your attendees Excel file.
  • Map the columns to the appropriate fields in the attendee entity or a custom entity if you created one.
  • Complete the import process to link attendees to the appointments.

Step 4: Verify and Adjust

  1. Verify the Data: Check the imported data to ensure that all attendees are correctly linked to their respective appointments.
  2. Adjust if Necessary: If there are any issues, you might need to adjust your Excel files and re-import the data.
