Use @mention in comments to tag someone for feedback

When you comment on a document, presentation, or spreadsheet and use the @-sign with someone's name, the person you mention receives mail with a link to your comment. Clicking the link brings them into the document and into the conversation.

Quickly find and respond to @mentions

In Word, Excel, and PowerPoint, when someone mentions you in a comment, you'll receive an email notification that includes a link that takes you to the comment in the file.

In addition, in certain versions of Word, Excel, and PowerPoint, the email notification also shows you a preview of the text and comment thread associated with the comment (also known as context preview), and you can respond to the comment directly from the email notification (also known as inline replies).
