Today we’re taking the next step and introducing Like and @Mention to workplace email in Outlook on the web. Microsoft Adds @Mentions and Likes To Outlook For The Web [blogs.office.com]

The new Like feature in Outlook on the web provides an easy way to visibly endorse a specific email and call it out as something worth attention—perhaps a statement or idea you support.

While the focus of Likes is on specific emails, the focus of Mentions is on specific individuals. When collaborating on email, it is common to call out a specific person for an action or request. Another scenario is adding a person to an existing thread for their attention—perhaps you are on a thread and know that the person who can answer a question was not initially included. Using the Mentions feature ensures that the person is not only aware of the request but is also included in the thread.

The Like feature in Outlook on the web will begin to roll out today to Office 365 First Release customers whose Office 365 plan includes Exchange Online. We expect the feature to roll out broadly to eligible Office 365 commercial customers starting in late October. The Mention feature will begin rolling out to First Release customers in mid-October and broadly to all eligible Office 365 commercial customers in mid-November.

In addition, our Outlook.com users who have been migrated to the new version of the service will start seeing Mentions in the December time frame as well.
