Hello,
If you are using an online storage service, then this error usually indicates that the local files or sync client are outdated. To help us identify the cause of this issue, we would like to clarify the following information:
- Are you using an online storage service? If yes, which service are you using? (OneDrive, iCloud, Dropbox, etc.)
- What is the exact error message that you receive? (A screenshot will be helpful)
- Are you using any applications that use the cloud as its storage location?
If you are using OneDrive, you just need to make sure that your computer is up-to-date using Windows Update (this should let you have the latest version of OneDrive). You can also try downloading OneDrive from the following link: https://onedrive.live.com/about/en-us/download/
Looking forward to your reply.
