Review for ReminderFox by Mark P
Rated 4 out of 5 stars
This is one of those really, really important addons if you're used to using Outlook. I simply could not go without the calendar/reminders feature, and was the one thing preventing me from ditching Outlook for good.
I'd definitely recommend this addon over the "Lightning" addon. It's a lot slimmer, simpler, and does exactly what I need it to.
