Google Calendar sync: cancelled meeting not removed when assigned user changes

[tothewine]

Hi everyone,

I’m working with EspoCRM and Google Calendar integration and I’m facing an issue with cancelled appointments.

ESPO Version 9.3.4
Google Integration Version 1.8.4

Scenario:

• EspoCRM is connected to Google Calendar (2-way sync)
• Meeting are created correctly in Google Calendar
• Sync is working fine for creation and updates

Problem:
When an appointment is cancelled in EspoCRM:

• I change the status (e.g. “Cancelled” / “Not Held”)
• A workflow reassigns the appointment to another user (e.g. Admin)

However:

• The event remains in the original user’s Google Calendar
• It is NOT removed or updated correctly
• It looks like Google does not detect the change of assigned user

Additional notes:

• The record is NOT deleted (deleted = 0), because I need it for reporting
• Option “Remove the event from Google calendar after removal in EspoCRM” is enabled
• Sync job runs correctly every 5 minutes (no errors)
• If I manually delete the appointment in EspoCRM, then Google removes it correctly

What I need:
I would like that when an appointment is cancelled:

• It disappears from the assigned user’s Google Calendar
  OR
• It is marked as cancelled in Google Calendar
  OR
• It is moved out of the active calendar view

Questions:

1. Is there a standard way in EspoCRM to sync cancellation status with Google Calendar?
2. Does Google integration support event status (confirmed / cancelled)?
3. Is changing assigned user supposed to update Google attendees?
4. Do I need a custom script or API call for this?

Any suggestion or best practice would be really appreciated.

Thanks in advance!
