Auffinden von Dokumenten und deren gemeinsame Nutzung mit anderen in Microsoft Teams-Kanälen oder Chats
Hello Christian G,
Thank you for reaching out to the Microsoft Community. My name is Eunice and I'm happy to help.
I am sorry you are experiencing this problem. It looks like the Files app in Microsoft Teams has been replaced by the OneDrive app in the left sidebar. This change is part of the updates in the new Teams experience. The OneDrive app now serves the purpose of accessing your recent files.
If you find this change inconvenient, you can provide feedback to Microsoft through their feedback portal to let them know how important this feature is to you. Kindly go to https://feedbackportal.microsoft.com/feedback
In the meantime, you can still access your recent files by navigating to the OneDrive app in Teams or by using the Search bar at the top to quickly find your files.
Let me know if you need more help.
Regards, Eunice
