I agree on the issue about the portal. I think they are trying to bring everything Microsoft into cloud which is really a pain. > I also get that they're going to make bucketloads of money getting their enterprise customers cloudified. Existing AD/Exchange deployments aren't just gonna jump over to Google, but they'll migrate bit by bit to Azure and pay nicely for it. I am wondering whether enterprises would go for GCP or other IaaS/PaaS for that matter if Exchange is something that can be replicated by Google. I used to work a company that uses everything Microsoft but really other than Office, I do not think I will miss anything if the company suddenly decides to choose other vendors. What is the situation in US/Europe that most enterprises hold so tight to Exchange?
