Get only the writable calendars from Outlook

I'm using this expression in a Dropdown:

Office365Outlook.CalendarGetTables().value

Which returns all the Outlook calendars I have access to.

However, when posting events to read-only calendars in Power Automate, I get the error:

Your request can't be completed. Read-only calendars can't be modified.

Thus, I'd like to filter the dropdown to include only the writable calendars.

How? Can anyone help?

The action CalendarGetTables() from outlook out of box connector cannot meet your request.

Here is the returned value from CalendarGetTables() function.

The workaround is to call the graph api using custom connecotr in canvas app instead of using the oob connector.

Thank you, do you know of a tutorial that is specific for the creation of a customer connector to O365 Outlook.
I'm navigating in the documentation, and finding interesting tutorials for weather prediction, sentiment detection, etc, but no graph api.

Hi @WebPortal ,

Please take a look at this blog.

The permissions assigned in the application should be different when using different Apis.

In your case, it should be-
