"Our installation turned out to be far more complex than anticipated through no fault of either Google Apps or ZumZum. I was therefore very impressed when they spent a considerable period of time working through all the issues and without even the hint of an extra charge. I have no hesitation in recommending them to anyone thinking of moving over and am happy to report that, so far, we have had no reasons to regret moving from Microsoft Exchange."
