Starting today, Office 365 customers with Enterprise plan can enable Yammer as the default social network in replacement of the SharePoint newsfeed.
To do so:
- Logon to your SharePoint Administration portal either using the administration menu on top right or using the direct URL (https://<your tenant>-admin.sharepoint.com/)
- Then go to the Settings option available on the left and choose Use Yammer.com service at the Enterprise Social Collaboration section on top of the page
Once done, the Newsfeed link available on top is changed to Yammer
End user may receive a request to confirm to go to Yammer
Then you will be redirected to your Yammer site.
