If you work in a company of any size chances are Microsoft technologies are the backbone of IT which means there's probably an Office 365 enterprise subscription.
Far removed from it's humble roots as a standalone productivity suite with Outlook's public folders as your primary collaboration source we now enjoy collaboration features that we'd never dreamed of back in the old days.
It really started with OneNote, then came SharePoint to extend the fun to other people and with acquisitions like Skype and Yammer, collaboration is almost a given in the modern enterprise.
But some features worked better than others and Microsoft has a bad habit of changing things without notice or letting features die on the vine.
For awhile it seemed like Yammer was going to be one of those withering features until recently.
In case you didn't know...
Yammer is a private social networking service that allows communication and collaboration between users in the same enterprise. Before the Microsoft acquisition access was limited to those within the same email domain. Microsoft tightened that up by using AD membership but there was still work to do in the 2 years since it became part of Office 365.
Today a major update was announced that allows even tighter integration on windows domains as well as new collaboration features and on the admin end the ability to merge yammer user domains. A handy feature with all those mergers and acquisitions going on in the corporate world.
The video below comes from Microsoft and does a better job of explaining the updates to the service than I could.
It's worth a look...
