Microsoft will release Office 365 multi-geo tenants to general availability in early 2018. You can then deploy Exchange Online, OneDrive for Business, and (later) SharePoint Online across multiple Office 365 datacenter regions. It’s good for data sovereignty, but won’t solve network problems.
Teams and Planner are excellent examples of new functionality that Microsoft can create using the toolkit of parts that exist within Office 365. The two applications have excited and delighted customers since their announcement, but the applications are not yet complete. Some challenges exist that Microsoft really needs to take on to round out functionality and capabilities.
