Calender event reminders are displayed on my desktop emclient but not my laptop emclient.   any ideas?

Hello John,
if you dismiss a reminder to the event on one device, it will not appear again (on neither device). This change will be synchronized to the event.
Or do you mean that NO reminder ever appear on your laptop?
Are both eM Clients running/opened at the same time?

Regards,
Olivia
