I am very new to VBA but need some VBA code to send a meeting request

I need some code for sending emails out based on referee appointments to emails which will be added later to column M. I need the email to send the appointed person all the information so they just need to "accept" or "decline" the appointment instead of emailling this spreadsheet out to everyone and waiting for them to email me back. If they could just click "accept" or "decline" it would make my life easier.

Many thanks for any advice received.
