I have looked and looked and cannot find a way to have Zimbra send emails for calendar reminders/notifications. I found this article from 2008 that indicates Yahoo had such a feature and since Yahoo Mail is Zimbra-based, I had hoped the feature had made it into Zimbra.
Yahoo Announces Major Update to Yahoo Calendar: Leverages Zimbra Technology
I am at version 6.0.6. This seems like such a fundamental function. Right now, if you aren't sitting in front of a computer, you get no calendar notification (ie. cell phone, pager, pop3/imap client, etc). For those of us on the road a lot, this is a major gap.
Does anyone know how to get Zimbra to send emails for calendar events?
