A Microsoft file hosting and synchronization service.
Hello Дмитро
I can see that you are encountering trouble with OneDrive sync.
First, please check whether you can access your files through OneDrive online.
If online access works, unlinking and reconnecting the PC may resolve a local sync configuration problem:
- Select the OneDrive cloud icon in the notification area.
- Select Help & Settings > Settings > Account > Unlink this PC.
- Open OneDrive again and sign in.
- If prompted that the folder already exists, select Use this folder.
If the same message remains, please provide the complete error code and confirm whether you can sign in at OneDrive online
Feel free reply back to this post and update me on this issue, I'll be happy to help.
