If you’ve ever had to desire to “like” an email, Microsoft has you covered.

The company is bringing both “likes” and “mentions” to Outlook email. A thumbs-up button will now grace emails in your inbox, and clicking it will send a notification to the email’s author.

These likes, which Microsoft says can be an “easy way to endorse an email,” will show up as a counter at the top of said email.

That’s taking a page from Facebook, but Microsoft’s also taken @mentions from Twitter.

“To use Mentions, simply add the @ symbol in the body of an email. This will bring up your frequent contacts as well as access to your directory. Select the person you want to highlight, and they will automatically be added to the To: line if they were not already included. In addition, their name will be highlighted in the message in blue and they will receive an @ flag in their inbox view next to the message. Furthermore, they can sort by their @ messages to ensure they respond to all messages in which they were mentioned,” says Microsoft.

In terms of availability, you might not have access right away:

“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.”

So, probably December for most of you.

Thumbs up? Thumbs down? Do you see yourself liking many emails?
