AgendaX is a great product. As a group calendaring solution, it is the best on the market. AgendaX just works. I have full faith in it.
AgendaX has worked so well for us for over 10 years. I have never had to learn anything detailed about it. I just upgrade it and it always works!
As for the single issue we've had in the last 10 years while migrating to Office 365, tech support has done a great job tracking and resolving the issue.
