When I was working in my last position we ran an Office 365 environment. It had all the features you could ever ask for and very few of the complications one is faced with in a local Exchange environment. Failover was taken care of for us, High Availability didn't involve 6 in house/colocation servers and when an outage did occur I didn't have to wade ankle deep into the shit storm that was an office without email. One slight annoyance, however, was when Gates and Co. decided to roll out new services. More often than not such new features were like a surprise birthday party. You were absolutely elated to see everyone there, but then you realized they invited Gary the office cynic (the views of this writer do not reflect those of all other staff, many of us love Gary and would be more than happy to invite him to our next party - ed.). One such example of this was Microsoft's implementation of "OWA for devices"
