Fix Microsoft Loop Component Mentions Not Sending Notifications

Product: Microsoft Loop / Microsoft OneNote
Device & OS: not provided
Scenario: Collaborating using Microsoft Loop components and attempting to notify team members via mentions.
Observed behavior: Mentioned users do not receive email or app notifications when tagged in Loop components, especially in embedded OneNote components.

Before you start

Ensure that the recipients have checked their email inbox and junk folders for notifications, and verify their current notification settings in Microsoft Teams or Outlook.

Solution 1Recommended

Verify Workspace Access and Share Links Directly

Ensure the recipient has permission to view the component and share the direct link as an immediate workaround.

Mention notifications may fail to send if the tagged user does not have proper access rights to the host workspace, page, or conversation.

Confirm user access

Check that the mentioned users belong to the relevant Loop workspace, OneNote notebook, or Microsoft Teams channel where the component is hosted.

Copy the component link

Click the 'Copy link' button located at the top right corner of the Kanban or Progress Tracker component.

Share and re-mention

Send the direct link to the recipient via chat or email. Once they access it, try mentioning them again inside the component.

Verify Workspace Access and Share Links Directly

Workaround Successful: By sharing the direct link, you bypass potential notification delays and grant the user immediate access to the component.

Solution 2

Test the Component Across Different Applications

Isolate the issue by testing if mentions fail only in OneNote or across all Loop-supported applications.

Solution 3

Escalate to a Microsoft 365 Administrator

If mentions consistently fail across all platforms, the issue likely stems from tenant-level Loop configuration policies.

Frequently Asked Questions

Why do mentions work in Microsoft Teams but not in OneNote Loop components?

Loop components embedded in OneNote may rely on different synchronization protocols and tenant policies compared to Teams chat. Testing the component directly in the Loop web app can help isolate if the issue is specific to the OneNote integration.

Does the recipient need to be part of the Loop workspace to get notified?

Yes, the mentioned user must have access to the specific workspace, page, or conversation. Without the appropriate viewing or editing permissions, the system may block the notification from sending.

Can guest users receive Loop mention notifications?

Notification delivery for guest users depends entirely on your organization's Microsoft 365 external sharing settings and Loop admin policies. If external sharing is restricted, guests will not receive mention alerts.
