A Microsoft file hosting and synchronization service.
Hello Lucas,
Thank you for posting this issue on the community forum.
As per your description, you have shared OneDrive folder and suddenly it changed name and empty folder.
I would like to recommend you some of the following workarounds for troubleshooting:
- You can re-share the same folder which you want to share.
- Ensure that when you share folders with Edit permissions, people you share with can add the shared folders to their own OneDrive. This lets them keep the folder alongside their own folders and items, easily move items between folders, and more easily work on it offline. Any updates they make sync with the shared folder, so everyone with access to the folder is up to date.
- To share OneDrive files and folders: Share OneDrive files and folders - Microsoft Support
Appreciate your understanding and patience.
