The clearest advantage, has been our ability to access the emails from anywhere, on pretty much any device, via the incredibly straightforward webmail interface built into Kerio Connect ... The only comment I can make is that connecting employees with better communication always saves time and money and improves business.Matt Bartlet, CEO Chord Electronics
For ease of day-to-day admin, I'd give Kerio nine out of ten, maybe even ten - and I'm not exaggerating. It took me a couple of days to get up to speed with the basic, everyday management of Kerio. The more detailed stuff took a while longer, but that was mainly to do with our own IT policies.Asim Syed IT Network Manager, Ryman Stationery
