Appointment Status Updated to Busy but Showing as Tentative in Outlook

What’s happening?

Appointments scheduled and updated to "Busy" status through Power Automate are showing as "Tentative" in Outlook calendar, despite reflecting correctly as "Busy" in CRM.

Reason:

This occurs because the "status reason" field used to update the appointment status through Power Automate is not supported for synchronization with Outlook. This behavior is by design.

Resolution:

The "status reason" field is not supported for synchronization with Outlook. This behavior is by design. For detailed information on supported fields for synchronization, refer to the following documentation:

• Fields synchronized between Dynamics 365 and Outlook
• Server-side synchronization

To ensure correct synchronization of appointment statuses, use only the fields supported for synchronization as outlined in the above documentation.
