How to Fix Microsoft Loop @Mentions and Notifications Not Working

Product: Microsoft Loop
Device & OS: not provided
Scenario: Collaborating with colleagues using @mentions and assigning tasks within a Microsoft Loop workspace.
Observed behavior: Users are missing from the @mention search, email alerts for mentions and tasks are inconsistent or absent, and the mobile app sometimes experiences delays or crashes.

Before you start

Ensure that all team members involved are using supported Microsoft accounts and have been granted appropriate access permissions to the specific Loop workspace.

Solution 1Recommended

Verify Workspace Permissions and Account Support

Ensure all users have the correct access rights and account types to be searchable and receive notifications.

Microsoft Loop relies heavily on organizational directories and workspace permissions. If a user is not properly added to the workspace or is using an unsupported account type, they will not appear in @mentions or receive alerts.

Check workspace access

Open your Microsoft Loop workspace, click on the 'Members' or 'Share' icon in the top right corner, and verify that the intended users are actively listed as members.

Verify account types

Confirm that you and your colleagues are operating on supported Microsoft 365 work or school accounts, as personal accounts may have limited notification capabilities.

Test in a web browser

Access Loop via your preferred web browser instead of the desktop or mobile app. Try mentioning a user there to rule out local application defects.

Frequently Asked Questions

Why are colleagues missing when I try to @mention them in Microsoft Loop?

This usually happens if the users have not been added to the specific Loop workspace, or if there is a sync delay within your organization's Microsoft 365 directory. Ensure they are invited to the workspace first.

How can I edit Loop notification settings for a corporate account?

You can manage Loop notifications by clicking the Settings menu (often a three-dot icon) in the Loop app, selecting 'Settings', and navigating to the 'Notifications' tab. Keep in mind that IT administrators may control some organizational notification policies.

Are email alerts guaranteed when a task is assigned in Loop?

No, task assignments in Loop may not generate notifications in every scenario. Certain task components might only sync silently to Microsoft Planner or To Do without triggering a direct email alert.

What should I do if the Loop mobile app crashes when checking notifications?

Ensure your mobile operating system and the Loop app are both updated to the latest versions. If the issue persists, try signing out and back in, clearing the app cache (on Android), or reinstalling the app to clear out corrupted local data.
