Scheduling "on behalf of" is emailing multiple wrong notifications to my colleague

[Billyrep]

I am sending out Zoom meeting notifications "on behalf of" a colleague (in Outlook). A few minutes after I send, my colleague is receiving the email notification that I have scheduled a meeting for her with the correct date and time. She then receives anywhere from one to five email notificaitons stating that I have scheduled a meeting for her with incorrect (and seemingly random) dates and times. None of them actually appear on her or my Outlook calendar (but I later delete these occurences in my Zoom calendar). I'm not sure why this is happening. I turned off all my email notifications and that seems to limit the number of wrong email notifications, but she still gets a few. Any guidance on how to fix this would be appreciated!
