Cannot open Planner within Teams

It sounds like your colleague is experiencing an issue with accessing the shared Planner in Microsoft Teams. Here are a few steps you can try to troubleshoot the problem:

1. Check Permissions: Ensure that your colleague has the necessary permissions to access the Planner. If the Planner is part of a team, she should be a member of that team.
2. Clear Cache: Sometimes, clearing the cache of the Teams app can resolve loading issues. Have her sign out of Teams, clear the cache, and then sign back in.
3. Browser Issues: If she is using the web version of Teams, it might be worth trying a different browser or clearing the browser cache. Also, ensure that the browser settings allow for proper loading of Teams.
4. Check for Updates: Ensure that both of you are using the latest version of the Teams app. Updates can fix bugs and improve performance.
5. Limited-access User Permission Lockdown Mode: If the Planner is stored on OneDrive, check if the Limited-access user permission lockdown mode is activated on your OneDrive site, as this can prevent access to shared files. If this feature is enabled, consider deactivating it.

If these steps do not resolve the issue, you may want to reach out to Microsoft Support for further assistance.

Hello @Liv Turner

Welcome to Q&A forum!

I understand this situation is really uncomfortable for you and your colleague while working together.

To ensure I fully understand the issue you’re experiencing, I’d like to confirm a few details:

• Are you the owner of this Planner? If yes, the owner can share this Planner again.
• May I confirm why your colleague lost access to this Planner?

I also want to suggest some troubleshooting steps that you can try to see if it works for your situation:

1/ Clear Teams Cache

This won’t delete any data, but it will refresh the app’s interface.

First, you need to quit Microsoft Teams completely and follow the detailed guidance in this article:

Clear the Teams client cache

After that, restarting your Teams again.

2/ Try Teams Web or Direct Planner Access

Go to tasks.office.com and log in.

If the plan loads there, the issue is with the Teams desktop client, not Planner

Test in Teams Web version: https://teams.microsoft.com/

3/ Update Teams

Ensure your colleague is running the latest version of Teams. Updates often fix integration bugs.

If the problem persists, follow these articles guidance steps to update

Update Microsoft Teams - Microsoft Support

4/ Reset or Reinstall Teams

• Go to "Windows Settings" -> "Apps" ->" Installed apps"-> "Microsoft Teams"
• Click on "Advanced options" -> Scroll down and choose "Repair" (you can tried to repeat this step several times)
• If that doesn't work, try to "Reset" (After that, you need to sign in again)
