When an event is added, updated or deleted - trigger mysteriously stopped working

Posted on by JM-14051638-0

Hi, I have a flow that detects changes in a secondary calendar, which pulls in a feed from our school calendar. It has been working fine, but now says there is a problem with the trigger, and the CalendarGetOnChangedItemsV3 request may not be supported. When I go to the flow and test it with the last trigger that worked, it still works. The raw input to the trigger in both the failed request and the last successful request is identical:

{
"host": {
"connectionReferenceName": "shared_office365",
"operationId": "CalendarGetOnChangedItemsV3"
},
"parameters": {
"table": "MYCALENDARIDGOESHERE=",
"incomingDays": 14,
"pastDays": 0
}
}

Any suggestions for where to go from here would be greatly appreciated!

Thanks

HI,

Can you tell what exact error you get for this trigger? Does user still have access to the calendar?

Have you tried to delete the trigger action and recreate it using the action When an event is added, updated or deleted (V3)?

Also just started experiencing this today- had a number of flows that were working perfectly and now getting an error: Your Office 365 calendar doesn't support the on change trigger.

This automation is highly utilized for our business, would appreciate any suggestions or feedback ASAP.

When more organizations face this issue, there can be an outage or new features impacted the behavior of the trigger or connector. In case you keep experience this issue, you can consider creating a ticket for Microsoft Support.

I'm getting this same error same error - Your Office 365 calendar doesn't support the on change trigger - with the "When_an_event_is_added,_updated_or_deleted_(V3)" trigger. Just started this morning; and I just created a post about it (only just now seeing that you posted the same thing earlier this morning.)

@André Arnaud de Calavon thanks for the suggestions. Yes, I still have access to the calendar. I will try to get more details (still new to power automate so finding it tricky!) The most detail I can find is:

Action 'When_an_event_is_added,_updated_or_deleted' failed.
Your Office 365 calendar doesn't support the on change trigger.
Error status code: badrequest

I'm not sure how to compare the requests (the ones that fail compared to when I test it and it works).

Think the best bet is just all of us opening tickets with Microsoft hoping it will be fixed or whatever change reversed.
