Given what I have seen thus far is that the "Change Management" required to introduce this is overwelming. Any large organization with a substantial user base is using many of the unique items in Windows based Outlook - how they expect this to be introduced without a huge loss of productivity and cost is beyond me. I have been looking at alternatives such as installing desktop Outlook and other email client options. The new Outlook is not ready for prime time and given what I have seen is years away from a development standpoint. I simply cannot understand why they would replace a robust tool with a toy.
