How can I receive email reminders for tasks assigned to me in Planner?

Receiving email notifications for tasks assigned to you in Microsoft Planner is not a direct, user-controlled setting within the Planner interface itself. The notification mechanism is governed by the broader Microsoft 365 ecosystem, specifically through the Microsoft Graph and the associated Office 365 subscription service. When a task is assigned to you in a Planner plan, the system typically generates an email notification automatically. However, the delivery and management of these emails depend on several integrated factors, primarily the configuration of your Microsoft 365 Groups and your personal notification settings in connected services like Microsoft To Do or the Planner mobile app.

The primary channel for these notifications is the Microsoft 365 Group associated with the Planner plan. Each plan is housed within a Group, and that Group has a shared mailbox. Assignment notifications are sent from this service. Therefore, if you are not receiving emails, you should first verify your membership in the correct Group and ensure that your email address within Azure Active Directory is accurate. Critically, you must check the Group’s settings in the Microsoft 365 admin center or via Outlook; an administrator may have configured the group to not send conversation or event notifications to members, which would suppress Planner assignment emails. For an end-user, the most direct action is to access the Planner plan via the web or mobile app, navigate to the "..." menu for the specific plan, and check for any "Plan settings" options related to email, though these are often limited. The more reliable check is within the Microsoft To Do application, as tasks synced from Planner can sometimes have their notification rules managed there under "Settings" and then "Notifications."

If the foundational Group settings are correct and notifications are still absent, the issue likely resides in mail flow rules, junk mail filters, or tenant-level policies. Corporate IT administrators possess the tools to diagnose this fully. They can examine the Group’s activity feed, audit logs, and message trace in the Exchange Online admin center to confirm whether the notification emails are being generated and where they are being routed or blocked. An administrator can also adjust the Group’s capabilities using PowerShell cmdlets, such as `Set-UnifiedGroup`, to ensure the `SubscriptionEnabled` parameter is set to true, which is necessary for these automated emails. For the user, a practical diagnostic step is to use the Planner mobile app, which often provides push notifications for assignments independently of email, confirming that the core assignment event is being registered by the service.

Ultimately, receiving email reminders for Planner assignments is less a feature you "turn on" and more a service you ensure is not disrupted. The process is automated but dependent on a correctly configured hierarchy of services: a healthy Microsoft 365 Group with notifications enabled, a synchronized user directory, and unobstructed email delivery. Persistent issues require administrative intervention to examine the tenant’s Graph notification settings and Exchange Online rules. For individual users, maintaining updated memberships in correct Groups and using the consolidated notification features in the Microsoft To Do app or the Planner mobile application often provides a more consistent and controllable alert experience than relying solely on email.
