SharePoint
2013 SP1 includes settings to configure Office 365 integration
Background: After I installed SP1 for SharePoint 2013 for My
production server. I surprised by seeing the new tab on the central administration
page with the name office 365.After I do research on this, I come to know the plan
of MS to keep the tab on central administration.
If you go to the SharePoint Central Administration soon after the installation of the SP1, you will see an important notification.
As well as a new link/option shown in the Quick Launch menu on the left or in the Central Administration home page
This 2 links provide you a way to configure a first level integration
with your Office 365 to use Yammer (as this now included on Office 365 Enterprise
plans) or One Drive for Business on Office 365.
