Word Combines @Mentions and SharePoint Online Sharing Links

Not a Word Expert By Any Means

I am a dedicated rather than expert Word user. The editor is something I’ve used most days since I first opened Word 2.0 in 1993 and concluded it was a better word processor than DECwrite, an editor that ran on VAX workstations at the time. Word 2.0 ran on a 286 PC with 4 MB of memory, so it’s fair to say that it was a lot cheaper to use than its VMS counterpart.

Word is Like an Old Slipper

Over the best part of three decades I have grown comfortable with Word. Most of the time, I use the same features and don’t go looking for new functionality unless I need to perform a task. Recently, I found that Word (click to run or Office 365 ProPlus, now horribly renamed as Microsoft 365 Enterprise Apps suite) combines @mentions in comments with the ability to share documents. The feature is useful when you collaborate to create documents, which I need to do often.

Comment or @Mention

Using version 2004 (build 12730.20150) of Word, I noticed that the old insert comment command is now Comment or @Mention. Clicking the command brings up the usual dialog to enter a comment (for example, “what horrible text – you need to change this!”) with the added option to insert an @mention.

Type @ and the first few characters of someone’s display name. Word checks to find the person to mention. It looks like Word uses Outlook’s auto-complete list of email addresses because I noticed names from outside the tenant that I had previously emailed (Figure 1).

You can also add an @mention comment from the right-click insert menu. 

Sharing for @Mentions

For good reason, @mentioning someone only works for documents stored in SharePoint Online or OneDrive for Business. After selecting the name, you can enter the comment. If that person doesn’t currently have access to the document, Word offers to give them access (share) so that they can open and view the comment and the associated text (Figure 2).

The standard sharing mechanism available in OneDrive for Business or SharePoint Online is used, so the document must be stored in Office 365. If you open the document properties, you can see the share access granted to the @mentioned person (Figure 3).

Email Notifications for @Mentions

People @mentioned in a comment receive an email notification to tell them that they should go to the document to respond. The notifications sent by Office 365 applications are becoming smarter. OWA users can respond to Yammer conversations without leaving the client, and the Teams missed activity messages are a different take on the same idea. @Mention notifications contain information to help the recipient decide how quickly they need to respond by including the context of the comment (Figure 4). And when the time comes to respond, the link opens the document in the browser positioned at the comment.

Updated Comments

Once you involve other people in a document, it is likely that multiple people will edit the document concurrently. Collaborative co-authoring is not new, but I was pleased to see how responses to comments appeared in documents soon after they were added. Updates are not immediate because they depend on the autosave mechanism to capture and distribute changes to everyone who has a document open, but responses show up quicker than they would in a document circulated by email.

@Mentions for All

According to this Microsoft support article, PowerPoint, Word, and Excel are supposed to have the same @mention capabilities. This is certainly true of the online versions of the apps, but I only see @mentions in the desktop versions of Word and PowerPoint. Adding the feature to the desktop version of Excel might be a little more complicated.


The Office 365 for IT Pros eBook does not cover the desktop or online apps. However, we use Word to write the book and this feature exploits the Office 365 sharing mechanism, so we thought you’d like to know about it.

  1. Doesn’t yet work with the Office Application on the iPhone when editing a document from my OnDrive.

  2. Tony, I understand that, but as an engineer in a K12 environment I’m not always at my desk, and the iPhone has the app it would be helpful. Yes, I could usethe Edge or native Safari on the phone, but the app is just more convenient.

    1. The app might be more convenient, but it’s usually behind the desktop and online versions from a functionality perspective.

  3. Hello,
    Do @mentions in comments work with Guests / External Users ?
    We have a strange behavior on our tenant because several users used the feature to collaborate with guests and all of a sudden it stopped working. Looking at MSFT doc I cannot find a place where it is clearly stated whether @mentions for Guests / External Users should work or not…
    Thx

    1. Sharing with guests absolutely works. I just tested this (again) to make sure. However, there are some gotchas in the system. I can’t @mention some p[eople in Microsoft who are already guests in my tenant…. I have bugged this problem and we shall shee what happens.

      1. Hi,Tony!
        May I ask if you managed to find out if @mentions to guests and external users (with whom you’ve specifically shared a document) should be working? MS documentation from last year seems to suggest it doesn’t; however, I’m curious that you’ve managed to verify that it does. If it does, are there any specific admin settings that need to be enabled for it to work across a tenant?
        Thanks!

      2. I just tested and was able to @mention a guest in a Word document and Word shared the document with that person.

      3. How about an external email with whom you’ve shared the document?
        Here’s the latest MS doc about using @mentions: https://answers.microsoft.com/en-us/msoffice/forum/all/mentions-for-comments-in-word-excel-and-powerpoint/1e4ab379-fd32-4247-b9f5-c2d62d1d74d4 (Last updated May 4, 2020), which states: ‘@mentions does not work with guest or external accounts (you cannot @mention such accounts nor can such accounts @mention in files outside of their tenant).’
        Looks like you’ve somehow circumvented the function’s documented limitations!

      4. Well, I don’t know what Microsoft intends to have happen. I can only report what happens in front of my own eyes.

  4. hi, in my organizaton some Apple user can’t @mention using Safari no Microsoft Edge, there is any restriction to @mention in Apple enviroment? Thanks, Leandro
