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.

Assign tasks using @mentions

In Word or Excel for web, you can use @mentions to assign a task to another user when you post a comment or a reply. When you create the task, it's tracked through all interactions and reassignments, so you can see its history. However, since tasks are only available at this time for enterprise users in Word and Excel for the web, you can't reply to, reassign, resolve, or reopen tasks in other apps. You can see the comment history in those apps, but you won't see the task history. For example, if you assign a task in Word for the web and later open the document in Word for the desktop, you'll see the comment, but not the task. If you reopen the document in Word for the web, the task is visible again and you can interact with it.

To create a task:

  1. Add a new comment or reply to an existing comment.

  2. Use an @mention in the comment. The option appears to assign the comment as a task to the person mentioned.

  3. Select the Assign to checkbox.

    Use an @Mention to assign a task

  4. Post the comment or reply. The person the task is assigned to will receive an email notifying them that they've been assigned a task. In the comment, they'll see the task assigned to them.

To reassign a task:

  1. Use an @mention in the response field.

  2. Select the Reassign to check box.

    Reassign the task

  3. Post the reply. The person the task has been reassigned to will receive an email notifying them that they've been assigned the task.

To resolve a task assigned to you:

  1. In the top of the comment, hover over the circle next to Assigned to you. A check mark appears in the circle.

    Click to resolve the task

  2. Click the circle with the checkmark to resolve the task.

To reopen a resolved task:

  1. Open the comments pane.

  2. In the top of the resolved comment, click the green circle with the checkmark.

    Click to reopen the task

Note: Tenants with conditional access will not be able to create @mentions. Please contact your IT Administrator for more information.

  1. On your device, go to a document that's saved in a SharePoint library or OneDrive for work or school.

  3. Type @ and the first few letters of the person's first or last name, and then pick the name you want (If they don't already have permission to open the document, you'll be asked to provide that).

Tip: To be more casual, feel free to delete everything except the person's first name in the @mention. To include more people, type @ again and mention someone else.

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).

If you're mentioned more than once, you'll receive the links in a single email.

Note: This feature isn't available for customers using Microsoft 365 operated by 21Vianet.

How to turn off context previews

Admins can use a SharePoint PowerShell cmdlet to turn off context previews:

  1. Install the latest version of the SharePoint Online Services Module for Windows PowerShell.

  2. Connect to your tenant using Connect-SPOService.

  3. Run the following cmdlet: Set-SPOTenant -AllowCommentsTextOnEmailEnabled:$false

    Note: Email notifications for comments made in file that are Rights Protected or marked as sensitive via DLP rules won't include a context preview or inline replies, regardless of whether the feature is turned on or off.
