Microsoft 365: Change Meeting Organizer via PowerShell Cmdlet in Exchange Online

Allows the administrator of an Exchange Online tenant to change the organizer of an existing meeting or meeting series via a PowerShell cmdlet. This can be used, for example, to maintain continuity and history of a long-running meeting series in cases where the meeting organizer has a new role, is on leave, or during the offboarding process. Once the meeting is transferred, the new organizer will be able to maintain all properties of the event including meeting time and recurrence, attendees, and description. Meeting attendees within the Exchange Online tenant will not need to re-RSVP and the existing event on their calendar will be silently updated with the new meeting organizer information.

A subsequent feature will enable users to to change the organizer via Modern Calendar in OWA, New Outlook, and Teams. For user-initiated transfers the new organizer must accept the meeting before the transfer completes.
