Hi there, For a business case I would like to know how many big company's use MS Exchange as their email platform. It would be (even more) excellent to also know what the top 5 big transport company's use also, like UPS, FedEx, TNT, DPD etc. I would prefer a source which can be "hecked/verified" or is official and "non MS". Hope someone has done a similar investigation :-) Many thanks in advance! Max Kattekamp. (Netherlands)
