Adding Comments and Using @Mentions in Excel

You can add comments to an Excel file at any time without pre-sharing it. If you use an @mention on an unshared file, Excel will prompt you to share it so the notification can be sent.

Excel allows users to insert comments locally or on cloud documents. Sharing the workbook is not a prerequisite for simply creating a comment.

However, the @mention feature relies on cloud connectivity. When you tag someone, they will receive an email notification containing a link to the specific comment, provided the file is saved to OneDrive or SharePoint.

1
Select a Cell

Open your Excel workbook and click on the specific cell where you want to leave a comment.

2
Insert a New Comment

Right-click the selected cell and choose 'New Comment' from the context menu, or navigate to the 'Review' tab on the ribbon and click 'New Comment'.

3
Tag a User

In the comment text box, type '@' followed by the name or email address of the person you want to notify. Select their name from the dropdown list.

4
Post and Share

Type the rest of your message and click the 'Post' button (the green arrow icon). If the file has not been shared yet, Excel will prompt you to grant the tagged user access to the file.

Adding Comments and Using @Mentions in Excel
Email Notification Delivery: Email notifications for @mentions depend on your organization's Microsoft 365 settings and the recipient's personal notification preferences.

Frequently Asked Questions

Do I need a Microsoft 365 subscription to use @mentions in Excel?

Yes, utilizing the @mention feature to send email notifications requires the workbook to be saved in OneDrive or SharePoint, which is typically tied to a Microsoft 365 account.

Why didn't the tagged person receive an email notification?

They might not receive an email if the file isn't saved to the cloud, if they lack permissions to view the document, or if their account's email notification settings have disabled comment alerts.

Can I share an Excel file after I have already added comments?

Absolutely. You can add standard comments to a local file at any time and share the workbook later via email, a cloud storage link, or a shared network drive.
