Hi I am looking for a suitable calendar client program running on Windows. It must be able to access a caldav server. I also want to able to add multiple reminders for any event similar to Google Calendar. For information on my Android devices I use aCalendar (with davcal) which is excellent. I am now trying Thunderbird which is my Windows email client. I find that I cannot send emails as reminders, only alerts. Also when I enter a new event I want to automatically have multiple reminders, both notifications and emails. To test reminders I added a Google Calendar. In Google Clendar I added an event with muliplte reminders. See GoogleCalendarReminders.jpg. When in Thunderbird I "Open" the event and saw ThunderbirdOpenEvent.jpg. This showed 4 reminders BUT did not say emails. I then in Thunderbird opened the event in "Edit" and saw ThunderbirdEditEvent.jpg. The reminder is shown as custom but only 1 reminder shown, the Alert/Notification. I repeated this with only email reminders on Google and no reminders are shown in Thunderbird. How do I get email reminders in Thunderbird? Thanks Chris
