Hi ​@Crystal.Darby66022 - Thanks for reaching out!

At this time, there is only the option to edit the main invitee’s email address from the meetings page here:
 

If another person was added as a guest, there are two things we can do here:

1. You can reschedule the event and update the email
2. You can edit the event in your Google calendar and add the guests email there

However, being able to make changes to guest emails is a good idea, I’ve passed this on to our product team to review! Let me know if you have any other questions.

Thanks, David, for your quick reply. I’m having the main invitee just forward his reminders to his contact. It’s the best and quickest fix I could find.
