A customer recently reached out to me asking for the service level agreement for Microsoft Online Services.
We have a detailed set of information on the Windows Intune Trust Center
http://www.microsoft.com/en-us/WindowsIntuneTrust/
if you do a search for service you will find this section.
The link takes you to you to : http://www.microsoftvolumelicensing.com/userights/DocumentSearch.aspx?Mode=3&DocumentTypeId=37
Which details in a number of languages the SLA for the Microsoft Online Services which include Intune along many others.
