Mastering the Art of Using @Mentions in Your Microsoft Office 365 Feedback

When you’re adding comments to a Word document, Excel spreadsheet, or PowerPoint presentation, Office 365 lets you mention another user using the “@” sign (like most chat apps). Here’s what Office 365 mentions are for and how to use them effectively.

Mentions only make sense when you’re working with other people, so although you can use them with a personal Office 365 (O365) subscription, you’ll need to add other people to that subscription for them to have much use. This means that mentions tend to be more useful within an organization where everyone has an O365 license.

You’re never going to use Word, Excel, or PowerPoint as chat apps, but that doesn’t mean you want to leave the file you’re reviewing to send the author a message. Previously, you could add comments to an Office file for anyone else with access to that file to read, but that relies on them opening the file and reading the comments. With mentions, you can proactively send someone a message.

That message might be a question (“Sandra, can you confirm these figures are correct?”), an edit (“John, this section is too wordy, can you trim it down please.”), or simply a comment (“Jean, love this slide, that’s really effective”). Whatever it is, a mention will automatically send that person an email alert with a link to the comment. No more waiting for someone to open the file “just in case” you’ve added a comment!

We’re going to demonstrate this with Word, but the process is exactly the same in Excel and PowerPoint.

Select the text you want to comment on and then click Insert > New Comment (or right-click the highlighted text and select “New Comment” from the context menu).

In the comment box that appears, type “@” and the name of the person you want to mention. Write out the rest of your message and then click the “Post” button.

And that’s it, you’ve mentioned someone.

The person you mentioned will receive an email alert that shows your comment, the text you commented on, and a button to take them straight to your comment in the document.

Mentions in general work in Microsoft’s mobile apps, web apps, and desktop clients for Word, Excel, and PowerPoint.

The email alert has additional functionality that will also show any comment thread, the surrounding document context, and give you the ability to reply to the comment from the email.

This additional functionality is available in the mobile apps and web apps for Word, Excel, and PowerPoint, and the Excel client (version 1911 or later for Windows, version 16.31 or later for Mac). Email alerts from the Word and PowerPoint client apps will get this additional functionality sometime in 2020.
