Outlook.com users, along with people who use the stand alone Outlook client, will be able to do more than just check their email starting today. Microsoft is rolling out the first third-party add-ins for those applications, featuring companies like Uber, PayPal, Evernote and Boomerang. Microsoft first announced plans to introduced those add-ins for Outlook at its Build 2015 developer conference in April.
Here's an example of how the Uber add-in will work:
"Need a ride to your meeting or event? No problem, set up an Uber ride reminder for any calendar event with a single tap. Prior to the time of your ride, you get an Uber reminder on your phone with the destination already set. Simply swipe the notification, confirm your Uber ride, and your car will be on its way! Starting today, the Uber add-in is available in Outlook 2013 and Outlook on the web for users with Office 365 and Exchange 2013 mailboxes. It's coming to users of the new Outlook.com within the next month.
Microsoft also announced that more add-ins will be coming soon from companies like Yelp, IFTTT and Wunderlist. in addition, the new features for Outlook.com that were first announced in May are now available for a broader number of users after first rolling out to a limited set of Outlook.com customers.
