The biggest benefit to O365 is not having to worry about the mail server going down, it is Microsoft’s problem not mine. In addition, the staff has the option of storing files they are working on in the office in the cloud and then they are able to access them from anywhere else and continue working on the file(s). Simplex-IT's thoroughness of explaining all the options available to us (discussing both the pros and cons) helped greatly in our making a decision of which option to choose. Did not feel that Simplex-IT pressured us toward the most expensive option but the best option for us, which was by the way not the most expensive. In my opinion, Simplex-IT takes the time to understand your business needs and then presents a couple of options they feel best suits your current needs, as well as your needs in the near future.
