A Microsoft file hosting and synchronization service.
Dear Bayver,
Good day! Thank you for posting to Microsoft Community. We are happy to help you.
As per your description, please let us cooperate and please don’t worry, we can work together to narrow down and resolve the situation.
Based on my test result, it seems I can meet the same behaviour as like you described above. When I move the Microsoft Teams Chat Files and Recordings to another folder and the Microsoft Teams Chat Files folder not updated to existing folder, it will another separate folder.
Here is my test screenshot for your reference:
I did research and I found the one possible reason is when you share the files to other users in the Microsoft Teams via Private chat, the files are stored in your OneDrive account with folder name “Microsoft Teams Chat Files” which creates a shared link so that user whom you shared file with are able to access it.
Your understanding and patience will be highly appreciated. I hope that you are keeping safe and well!
Sincerely,
Waqas Muhammad
