Notes: 

If you don’t have Microsoft 365 and you need the OneDrive for work or school sync app, you can download it for free.

Make sure that none of the files you want to sync are larger than 2GB. If you see an error message such as "This file is too big to upload" or "Reduce the size of this file to upload to..." try reducing the size of a file by zipping it. You may be able to reduce the file size of a picture.

Make sure the entire file path, including the file name, contains fewer than 250 characters. An example of a file path is:C:\Users\<UserName>\Pictures\Saved\2014\January\Holiday\NewYears\Family… 

Shorten the name of your file or the name of subfolders in OneDrive, or select a sub-folder that's closer to the top-level folder.

You may have sync conflicts if you're uploading multiple files on the OneDrive for work or school site at the same time, or if you made changes in your OneDrive for work or school folder on another PC that is syncing at the same time. Sync issues can also occur if you edit files offline.

To reduce sync conflicts, rename the edited files or folders to something new or unique, and then save it again.

Try to open the file or folder and make sure that you have permission to save a copy of it. If you're having problems seeing a file on a network, contact your network administrator.

If you don't have enough disk space, you can either move or delete files (here are some tips about how to free up disk space), or you can download fewer files by choosing which OneDrive folders to sync to your computer.

Follow these quick steps to repair a sync connection with OneDrive for work or school, and see if that fixes your sync problem.

If you’re having problems with a synced library folder, it’s sometimes simplest to just stop syncing the library, and then Sync files with OneDrive in Windows, as if for the first time.

If you are unsure of your library path, visit your SharePoint Team Site, and browse to your documents: the URL is your library path.
