I am trying to create a calendar event with email notification using my HTC desire, but I can't figure how to do it. I tried both the built-in calendar app as well as mobile Google calendar website. How can I make it work?
For the Google Calendar website, desktop version (the following doesn't apply to mobile version of the website, so you must request desktop version of the page from your mobile browser):
Edit or create your calendar event, under event color selection you'll see Reminders, by default you'll have an email sent 10 minutes before the event start time.
The following is for the Google Calendar app:
Open your calendar event, go to Reminders, then tap the triangle selector under Notification, you'll see there is an Email option too.
If there is no reminder set, tap Add reminder first, or edit your event (the pencil icon).
