Outlook events sent to a google calendar - event ids change unexpectedly?











up vote

I am creating a meeting series from an outlook client, on an office365 mailbox.
The invited user is on g-suite (email, calendar...).



My code connects to google calendar via the API and periodically checks of event changes new events cancelled etc.



I store the event ids in my database and use them to match to the event IDs I read from google calendar.



When a whole meeting series is changed - for instance a weekly series gets a new starting time - the event IDs returning from google calendar APIs - change!



I am not sure if the IDs are generated by officeoutlook or by g-suite.
I am not sure what's the right way to match the events I stored with their old IDs, to the new events coming in.

          If you read the Google API Documentation, it states that recurring events are composed of instances. The recurring event is a parent and individual instances are its children. Each child has a recurringEventId which identifies its parent. Their individual instance ids might change when they are changed.
