The Office 365 team recently completed Office 365 Preview Service Descriptions that you can access on TechNet. Most pertinent to this blog is the Exchange Online service description. This isn't help documentation, but rather these are documents that describe the features and plans available to Office 365 customers. A few of the features highlighted are the following:

  • Permissions
  • Message Policy
  • Protection
  • Mail Flow
  • Reporting
  • Mobile Devices

Other service description documents include those for Lync Online and SharePoint Online.
