Question details
The user wants to know if it is possible to tag or @mention external guest accounts within the comment sections of Word, Excel, or PowerPoint documents.
- Product
- Microsoft Word, PowerPoint, Excel
- Device & OS
- not provided
- Scenario
- Collaborating on documents with external or guest users and trying to notify them by tagging them directly in document comments.
- Observed behavior
- Guest accounts successfully appear as suggestions when using @mentions in Microsoft Teams, but they do not show up as suggestions in Word, Excel, or PowerPoint comments.
Verify that your Microsoft 365 organization settings allow sharing documents with external guest users, and ensure you are connected to the internet.
Understand Mention Limitations and Use Alternative Notification Methods
Currently, Microsoft 365 does not support @mentioning guest users in Word, Excel, or PowerPoint document comments. You will need to use a workaround to notify external collaborators.
While guest accounts can be successfully mentioned in Microsoft Teams, this identity resolution functionality does not yet extend to Microsoft 365 document applications. When typing '@' in the comment box of Word, Excel, or PowerPoint, the system only pulls suggestions from your organization's internal directory. Guest suggestions will not appear.
Share the document link in a Microsoft Teams chat or channel where the external guest is already a member, and @mention them directly in the Teams message to notify them of your updates.
Click the 'Share' button in the top right corner of Word or PowerPoint, enter the guest's email address, and include a message directing their attention to the specific comments.
Navigate to the official Microsoft Feedback Portal online, search for 'mention guests in comments', and upvote existing requests to encourage Microsoft to implement this feature in future updates.

Frequently Asked Questions
Why can I mention guests in Microsoft Teams but not in Word?
Microsoft Teams and Microsoft 365 desktop or web applications utilize different directory syncing mechanisms. Currently, document comments in Word, Excel, and PowerPoint only support fetching user profiles from your organization's internal Active Directory.
Will an external user get an email if I type their full address in the comment?
No. Manually typing an email address after an @ symbol in a Word or PowerPoint comment does not trigger the automated email notification system for external users.
Is there any plan to support guest mentions in Microsoft 365 comments?
Microsoft has not provided an official timeline for this specific feature. Users are encouraged to vote on this functionality in the Microsoft Feedback Portal to prioritize its development.
