Microsoft today announced that they are bringing the concept of Like and @Mention to workplace email in Outlook on the web.
To Like a message in Outlook Web, simply click the thumbs-up icon in the reading pane. This turns the icon from gray to blue, notes within the email that you liked the message and adds a thumbs-up icon in the email list view. Anyone on the thread can Like a message, and their Likes are identified and captured within the message as well. If someone likes your email, you’ll receive a notification letting you know.
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.
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. 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.
