Thank you for posting in Microsoft Q&A Forum.
Regarding to your question, for your information: currently, Microsoft Teams does not support directly changing the meeting organizer after a meeting has been scheduled. When a meeting is created in Microsoft Teams, the organizer is permanently associated with that meeting. This design ensures consistency in permissions, ownership of meeting assets (such as recordings and attendance reports), and integration with calendar systems. Please kindly refer to this detailed official information article and topic about Change the organizer, it will provide you with official suitable information about your concern.
For the workaround, I'd suggest you a few options which may help your concern:
1- Delegate access or convert the mailbox to shared mailbox
- Before the organizer leaves: The organizer or IT can assign a delegate via Outlook to manage meetings.
- After the organizer has left: -IT administrators can grant “Full Access” and “Send As” permissions to a new responsible person. -Alternatively, convert the original mailbox into a Shared Mailbox and assign ownership to the new organizer. -The delegate can then open the calendar, edit meeting details, add/remove attendees, or cancel the meeting.
For the delegate article, you can follow: How do I access the mailbox (Enterprise, Midsize, Education)
For the convert shared mailbox, you can follow: Convert a user mailbox to a shared mailbox
Note: The organizer name will still appear as the original person, therefore, I'd recommended to add a note in the meeting invite such as: “This meeting is now managed by [New Organizer Name].”
2- Recreate the meeting if full control needs to be transferred, the most effective approach is to ensures clarity and avoids confusion about who is managing the meeting logistics:
- Cancel the original meeting.
- Have the new organizer create a replacement meeting with the same details.
- Notify participants that the new meeting supersedes the previous one.
- Copy important information from the old chat and paste it into the new meeting or a shared document.
- Re-share relevant files in the new meeting invite or channel.
3- If that user has left the company and the account is being deleted calendar items are immediately deleted when a user account is deleted and cannot be restored, even if the account is recovered. Meetings organized by that user will no longer exist in the system.
Additional Notes:
*Join links and conference IDs will change with the new meeting.
*Ensure meeting rooms and external participants receive the updated link.
*If recordings or transcripts exist, IT should transfer them from the original organizer’s OneDrive or SharePoint.
*For important recurring meetings, consider using a dedicated service account to avoid disruptions due to staff changes.
