    • Event title matching the event type name
    • Client details in the event body
    • Correct date, time, and timezone

Troubleshooting

Authorization failed? If your organization uses Microsoft 365 with conditional access policies, your IT administrator may need to grant consent for ChronSync. Contact your admin if you see an "admin approval required" message.

Events not appearing? Verify that you connected the correct Microsoft account. If you have both a personal and work account, make sure you chose the one with the calendar you use for scheduling.
