Data is a double-edged sword—when protected and used correctly, it’s one of an organization’s greatest assets, but when left unprotected and vulnerable, it can be
an organization’s greatest threat. 
Office 365 professionals introduced at Ignite the ability to assign workload-specific service administrator roles to IT administrators for Exchange Online, SharePoint Online and Skype for Business Online, and announced yesterday the capability is now available to O365 users.
Organizations with Office 365 can flexibly assign permission and roles to address varied company structure and Office IT responsibilities.
Instructions for how to configure the admin roles are available here.
