I've tried Evolution 2.30.3 from Jacob's ppa on Lucid and the version of 2.30.3 in Maverick beta, they differ and both have significant shortcomings. You can't right click on an email and create a meeting, event or task, for example. Some settings don't work in the Maverick version -- (un)compress weekends in month view, for example. No alarms for events just adds to its woes.
If evo is not working reliably in Maverick, I'll stick with 2.28.3 in Lucid.
