Microsoft Bookings - Appointment Reminder not working properly

Occasional Visitor
Some of my clients do not receive the booking confirmation and the reminders. I checked the trace in the eac and some are sent and some just do not appear there.

We are also having this same behavior. Any suggestion from others?
Also experiencing this problem. Customers don't receive reminders but our internal staff do..

I'm experiencing the same issue. I set reminders to go to all attendees. I got the reminders but not the clients. I used message trace in Office 365 to search for all emails sent from the calendar email address and it confirmed that the reminders emails were sent only to me (staff) and none went to the clients. Issue is only with the reminder emails. The confirmed emails the clients receive those. Definitely there is an issue that needs to be fixed.
