Microsoft announced this week that’s it’s bringing a few popular features from social media to your email inbox. Moving forward, Outlook will let you Like specific emails and even @Mention your friends and colleagues.

Once the new features go live, you should see a small thumbs up icon show up at the top of whatever email you’re reading. You’ll be able to see which messages you’ve already liked from the regular inbox view. Outlook will also send you a notification if someone likes one of your emails.

As for @Mentions, Microsoft notes that this could be particularly useful in longer chain messages for getting someone’s attention. Just type the @ symbol and Outlook will offer up a list of your frequent contacts. Pick a name and they’ll get a notification in their inbox so they don’t miss it. Tagging someone in an email will also automatically add them to the list of recipients if they weren’t there already.

The option to Like an email should be available starting today for any Office 365 First Release customers with plans that include Exchange Online. A broader rollout for regular Office 365 users is coming later this month. Meanwhile, Mentions will hit First Release accounts in mid-October and reach everyone else next month.
