This section describes how to like items and add favorites in the add-in for Outlook:
Liking something communicates to others that you approve or support a posted item. Once you like something, a You like this link appears on the item. As likes accumulate, the link text changes to, for example, You and 1 person like this, You and 2 people like this, or 2 people like this, as the case might be. Click the link to open a dialog showing who has liked the item.
When you unlike something, the check mark that appears next to You like this is removed and the message's like count is reduced, or, if you were the only person to like the item, the like link is removed entirely.
Marking an item as a favorite makes it easy to locate—you can find it on the Favorites panel or filter many panels to show only favorites. The Overview, Collections, Conversations, Social Objects, and Documents panels all provide a Favorites filter, which you can use to filter out all items except those you have marked as a favorite. When you show groups on the People and Groups page, you can filter your list of groups by favorites, too.
Click the like link text below the message—for example, You and 1 person like this—to open the View Like dialog. The View Like dialog lists the people who like the message.
The quick way to unlike an item is to click its Unlike link. Here is another way to unlike an item:
