Fix Microsoft Planner Notifications Not Working for Guest Users
Question details

- Device & OS
- not provided
- Scenario
- Accessing and collaborating on a partner's Microsoft Planner plan as an external guest user.

Verify that your Planner notification settings are fully enabled and check your email client's spam or junk folders to ensure alerts are not being filtered.
Report Guest Notification Limitations to Microsoft
Since missing notifications for guest users is a known system limitation, the most effective action is to submit detailed feedback to the Planner development team.
Guest users often face restrictions with Microsoft Planner notifications, even when all account settings appear correct. Because this is an infrastructure limitation, reporting the exact scenario directly helps the development team address the gap.
Log in to the Microsoft Planner web application using your guest account credentials.
Click the gear icon located in the upper-right corner of the Planner interface.
Select 'Send Planner Feedback' from the dropdown menu. Provide a detailed report including your guest account type, the affected external plan, your notification settings, and specific examples of alerts you did not receive.

Manage Project Tasks with WPS Spreadsheet
If external limitations in Microsoft Planner disrupt your team's workflow, consider organizing and tracking cross-organization tasks using WPS Spreadsheet. It offers a highly compatible, lightweight, and free alternative to standard Microsoft Office tools.

Frequently Asked Questions
Why do my Planner notifications work in my own environment but not as a guest?
Microsoft Planner handles internal and external routing differently. Guest user profiles often lack the specific Exchange Online mailboxes or permissions required to trigger cross-tenant email and push notifications.
Can I manually turn on notifications for an external plan?
You can check your notification preferences by clicking the gear icon in Planner and selecting 'Notifications'. However, even if 'Someone assigns a task to me' is checked, guest access limitations may still block delivery.
Are push notifications supported for guest users on the Planner mobile app?
Generally, push notifications on the iOS and Android Planner apps are subject to the same cross-tenant limitations as email alerts. They may not function reliably when logged in as a guest.
