Question

Links to Classwork modules, published in Channel General, don't work (module is published and everythink works there)

Answer 1

Hello @Magdalena,

Thank you for reaching out to Microsoft Q&A Forum!

Based on screenshot you provide, the error message “There was a problem reaching this app”, this typically occurs when the Teams client cannot properly load the Classwork app. This issue is often related to cached data, account permissions, or underlying Microsoft 365 group configuration.

Firstly, to narrow down the root cause and provide the most effective solution, can you help me confirm some information:

• Is this problem occurring only in the desktop app, or also in the web app?
• Is this issue affecting all users, or just specific individuals or roles (e.g., students vs. teachers)?
• Are you trying to access the module on a new device or browser?

In the meantime, please try my suggestions below:

1. Try Microsoft Teams Web App
Open Teams in a private/incognito browser window and access your Class Team. Click the module link from there. If it works, the issue is likely with the desktop app cache.

2. Clear Teams Cache
Clearing the cache often resolves persistent local issues.

• For Windows:
• Close Teams completely.
• Navigate to %appdata%\Microsoft\Teams\Cache and delete the contents.
• Restart Teams.

Follow these articles for more details (I noticed your post is under the pl-pl locale, so I’ve included Polish language Microsoft article and English article links for your convenience):

If the issue persists, I strongly recommend you contact your school’s IT administrator to check:

• Group Ownership: Ensure the Microsoft 365 group linked to the Team has an active owner.
• App Permission Policies: Confirm Classwork is allowed and assigned correctly in Teams Admin Center.

We appreciate your kind patience and understanding that sometimes the initial response may not immediately resolve the issue or there may be some misunderstandings about your scenario, but we would love to hear updates from you and find out further suggestions.

Best Regards.
