Having used Zoho, the best thing I can say about their service is that it's not gmail. It's a very mediocre offering. Most email is but they have an all-in-one service that's entirely "meh."
The navigation was difficult, configuration and user management was a complicated mess, the service desk was slow and difficult to use, etc. So, by "meh," what I really mean is "No compelling differentiators and not well organized, making it an entirely unremarkable offering."
