Using Classic Outlook on Windows for personal email, calendar, and contact management
Hello SydenyKneller,
Thanks for choosing Microsoft Community.
According to your description, may I carefully confirm with you, if you are the meeting owner, what is the meaning of you cannot edit the invite? Based on our knowledge and experience, there is not such a option to delete the meeting unless you cancel the meeting, however if you cancelled the meeting, the meeting participants will receiving a email (notification) claims that this meeting has been cancelled which the meeting won't show up in their Outlook calendar.
Kind Regards,
Tommy
