Graph API Create Event - Sender was changed, not using the organizer.

Samuel Tse 21

We have been using Graph API to create meeting/event. The meeting invitation email has been sent using organizer's email. However, I noticed something had changed in the last month or two. To give a bit more context, our application allow the general public to book an appointment to meet with the staff in our advising department. In order to actually allow the meeting to be created in the advisor's Outlook calendar, the application has to use an access token generated by an internal service account, which all advisors share their calendar to.

With that information, the meeting invitation email that's sent to the public user used to have the advisor (userPrincipalName) as the sender. With the last month or so, I noticed the sender is now the service account used for the access token.

Have anyone experience this behaviour? or know how to address it?

This is the end point we use: https://graph.microsoft.com/v1.0/users/${userPrincipalName}/events

Thanks

Sam

I am curious if you have an answer. I am looking for something similar. I set up a calendar event. Using internal service account- just like you. I set the organizer to a "real" person and invite that person. Later steps are a client confirmation, where I use API to update them as attendees. But it always sends as the internal service account. Looking for a work-around.
