Microsoft Teams Planner Tasks have Disappeared

Question

Microsoft Teams Planner Tasks have Disappeared

Gillian Stine 0

I have been having this issue for the last week, but all of my Teams Planner tasks have disappeared from the app. I've tried restarting my computer, toggling different filters, using the web version, and seeing what tasks are assigned to me and nothing is populating. There are also no "Completed" tasks that are populating, which I know is wrong because each of my buckets have at least 10 completed tasks. Is anyone else having this issue? Does anyone know how I can fix this to see my tasks again?

Dear @Gillian Stine,

I hope you’re having a good day.

Thank you for reaching out. I understand that all of your Planner tasks in Teams have suddenly disappeared, including completed tasks, and that you’re seeing the same behavior across both the desktop app and web, that can definitely be concerning.

Based on your description, this may not be a simple display or filter issue, but rather something related to how the tasks or plan are being accessed. To better understand what’s happening, there are a few things I’d suggest checking:

Check directly in Planner (web):

Go to https://tasks.office.com and see if your plans and tasks are visible there. This helps confirm whether the data is still present.

Confirm your access to the plan:

It’s possible your access or membership to the plan may have changed. If you’re no longer part of the plan, tasks may appear empty.

Check with a teammate:

If possible, ask someone else from your team if they can still see the same tasks. This helps determine whether it’s affecting only your account or the entire plan.

Verify the Team / channel setup:

If the Planner tab was recently updated, reconnected, or linked to a different plan, it may be pointing to a different (or empty) board.

Since completed tasks are also missing, this makes it less likely to be a filter or client-side issue, and more likely related to access or how the plan is being loaded.

If you’re able to confirm the above and the issue persists, it may be worth reaching out to your IT admin so they can check plan membership or any recent changes on the backend.

Feel free to share what you find after these checks, I’d be happy to help you look into it further.

Warm regards,

Hi Liora,

I had to reach out to our office's IT team because the recommended options weren't yielding any results. Microsoft ended up having an outage that affected Planner, but the outage has been fixed and I am able to access Planner now.

Hi Gillian Stine,

Thank you so much for getting back and sharing the update, I really appreciate it.

I’m glad to hear that your IT team was able to confirm it was related to a service outage and that everything is now working again. That also helps explain why the issue appeared across both desktop and web, and why even completed tasks were missing.

Thank you again for taking the time to update the thread, this will definitely help others who might run into a similar situation.

Please feel free to reach out again if you run into anything else, I’ll be happy to help

This behavior matches a known service issue where some users are unable to view the Planner app and its tasks in Microsoft Teams (issue ID: TM1261085). In that incident, Planner plans and tasks were still available in Planner on the web, but the Planner app inside Teams stopped showing content for affected users.

Because this is a service-side problem, local troubleshooting (restarting the computer, changing filters, or switching to the Teams desktop/web client) does not resolve it. The tasks and completed items are not deleted; they are just not being surfaced in the Teams Planner experience for users routed through the affected infrastructure.

Recommended actions:

Continue using Planner directly in the browser (Planner on the web) to access plans and tasks while the Teams-side issue is active.
Contact the Microsoft 365 admin to check the Microsoft 365 Service health dashboard for the latest status on issue ID TM1261085 (or similar Planner/Teams advisories) and follow any remediation or timelines provided there.
If the issue persists and no active advisory appears, have the admin open a support ticket with Microsoft, referencing that some users cannot view Planner in Teams while it remains available on the web.
