Automatically provisioning service accounts does the following:
Creates new service accounts based on selected Microsoft Office 365 services
Configures required roles and other settings for the new service accounts
Automatically provisioning service accounts eliminates the need to:
Manually create and configure Office 365 user accounts
Manually assign Exchange Online roles
Manually add SharePoint Online site collections
Manually assign SharePoint Online and OneDrive for Business site collections administrators, one by one
To automatically provision service accounts, you can:
Create a Delegate Account for Exchange Online.
(For EU and U.S. sites) Use the the OAuth authorization framework to create an authorized account for Exchange Online.
Create a Delegate Account for SharePoint Online and OneDrive for Business.
There are three ways to begin a provisioning flow:
Use the pop-up wizard that appears at sign in.
On the Dashboard screen, hover over Exchange Online, SharePoint Online, or OneDrive for Business that you want to protect and click Provision in the tooltip that appears.
Go to Administration > Service Account. Click Add and select Exchange Online or SharePoint Online.
