Microsoft announced a new feature for Office 365 called Connectors. It looks like a great way to hook into APIs of other services such as GitHub, Trello, Twitter, MailChimp, Wunderlist, SalesForce, and others. Interestingly, the feature is part of the Groups feature in Office 365.
This allows you to pull Twitter feeds or other content from these third party services into your shared inbox, calendar, and other Office 365 features. There are over 50 Connectors available today. You can create your own group and check them out or add them to an existing group you might have and access the feature by yourself or collaboratively with other group members.
Connectors can be found in Office 365 by clicking on Connectors on the navigation bar from your Group in Outlook on the web. More information on Connectors can be found in this Support.Office.com article.
