Graph Event orphaned series

Thomas McCarthy 1

Hi all

i have a strange issues, i am migrating users from one tenant to another and i need to update Teams Calendar events, i have a scripted that is working for this.

the issues is some Calendar events dont appear in the graph pull for the users, this seems to be for meeting where the seriesMaster has been deleted, all other instances still exist.

is there anyway to find all instances of the series without the master?

thanks
Tom

@Thomas McCarthy

Could you please share the request and response for the call that you are making? Please make sure you have removed any PII.

I am performing a get request to the below and looping over each page to get all events.
https://graph.microsoft.com/v1.0/users/<userid>/calendars/<calendarid>/events

I could share the responses but it will not show any information as the series master was deleted by the user and is not in the get response.
All other instances of the recurring meeting still exist in the user's calendar with the exception of the series master, and I am unable to access these meeting instances from the graph API as it requires the Master event id to pull the instances of that event.
