Sending a Welcome Message to New Employees Part 2

Recently, I wrote about how to use PowerShell to send a welcome email to new employees together with attached ICS files for corporate events. Although new employees can add the ICS files to their calendars (so the solution works), simply inviting employees to attend those events by updating the participant list with PowerShell is an easier and better approach. This article explains how to find calendar events, update participant lists, and update events with the Microsoft Graph PowerShell SDK.
