How to Fix Microsoft Project for the Web Not Sending Task Assignment Emails

Product: Microsoft Project for the web
Device & OS: not provided
Scenario: A project manager or team member assigns tasks to users in Project for the web, expecting an automated email alert to notify the assignee.
Observed behavior: The email notification for the assigned task is never delivered to the user's inbox, even though in-app notification preferences are turned on.

Before you start

Verify that the affected users have checked their Spam or Junk folders, and ensure their email addresses are correctly configured within your organization's Microsoft 365 directory.

Solution 1Recommended

Verify Notification Settings and Task Assignments

Ensure that notifications are properly enabled and tasks are assigned to the correct, active user accounts.

Before escalating the issue, it is crucial to rule out basic configuration mistakes. Sometimes, users may have accidentally turned off their notifications, or tasks might be assigned to a deactivated or incorrect user profile.

Check User Settings

Have the affected users log into Project for the web, click on the Settings gear icon, and verify that email notifications for task assignments are turned on.

Verify Task Assignment

Open the specific project, click on the assigned task, and confirm that the assignee matches the exact and active Microsoft 365 user account.

Test with a New Task

Create a brand new test task, assign it to a user, and wait a few minutes to see if the notification triggers.

Verify Notification Settings and Task Assignments

Important Distinction: Make sure you are checking settings for 'Project for the web' and not 'Project Web App (PWA)', as they are distinct products with different notification configuration menus.

Solution 2

Open a Service Request with Microsoft Support

If settings are correct but emails still fail to deliver, the issue likely involves Microsoft's backend mailing service and requires a support ticket.

Frequently Asked Questions

Why are Project Web App notification settings different from Project for the web?

Project Web App (PWA) and Project for the web are built on entirely different backend architectures. PWA uses SharePoint settings, while Project for the web integrates with Microsoft 365 Groups and Dataverse, which means their notification delivery methods and configuration pages are completely separate.

Can standard team members contact Microsoft Support to fix this email issue?

Generally, no. Only a designated Microsoft 365 global, billing, or service administrator can open a service request in the Microsoft 365 admin center. Standard users should report the issue to their IT department.

How long does it take for notification settings changes to apply?

While some changes take effect immediately, modifications to user profiles, group assignments, or global notification settings in Microsoft 365 can sometimes take up to 24 hours to sync fully across all integrated services, including Project for the web.
