Hello SydenyKneller,
Based on your initial post, you find this calendar in deleted item, we tried it, if you have cancelled a meeting then it will move it to the Deleted Items in Outlook. Since meeting has deleted recipients will receive a cancellation like these screenshots show:


Further, even the meeting organizer move it back to inbox folder, recipients still will see this meeting has cancelled, therefore we suggest you create a new meeting. Meanwhile, may I carefully request you provide the participants’ screenshots in your end? Further, if you are not available to edit it, we kindly suggest you create a new meeting again.
Your understanding and co-operation will greatly appreciate.
Kind Regards,
Tommy
