Change the meeting organizer

Outlook doesn't currently support directly changing meeting organizers but try this workaround. 

1. In  Calendar, select the meeting you'd like to change owners, and go to Home. 

2. Select   Respond > Reply All. 

3. In the reply, press Ctrl+S or go to File > Save. 

4. Close the reply and go to Mail > Drafts and open the reply message. 

5. Change times or other specifics, and select Send.

The original owner can now delete the old meeting.
