Here are some solutions to common problems keeping your OneDrive in sync.
Try restarting OneDrive.
Click Start, enter OneDrive in the search box, and then click Microsoft OneDrive. This opens your OneDrive folder, and also starts the OneDrive service.
Click the OneDrive icon in the menu bar.
Click Quit OneDrive.
Use Spotlight to search for OneDrive and open it.
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 accessing a file on a network, contact your network administrator.
This can happen if you're uploading files on the OneDrive website at the same time, or if you made changes in your OneDrive folder on another computer that are syncing at the same time. Rename the file or folder, and then try to add it again.
Zip or resize the file so that it's less than 2 GB and try again. If you added a OneNote notebook, make sure each section is less than 1 GB.
Get more storage space or move files you don't need in OneDrive anymore out of your OneDrive folder.
Change its name so that it doesn’t begin or end with a space, end with a period, or include any of these characters: / \ < > : * " ? |
These names aren't allowed for files or folders: AUX, PRN, NUL, CON, COM0, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, LPT0, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, LPT9
If you have it open in an app, save it and close the app, and then try to add it again.
Make sure that the removable media device is correctly connected to the computer, and then try to add the file again.
The entire path, including the file name, must contain fewer than 255 characters. Shorten the name of your file or the name of subfolders in OneDrive, or select a subfolder that's closer to the top-level folder. Then follow these steps to start syncing your OneDrive folder on the computer again:
Click Start, enter OneDrive in the search box, and then click Microsoft OneDrive. (On a Mac, use Spotlight to search for the OneDrive app.)
Follow the steps to select your OneDrive settings again, including picking the location of your OneDrive folder and choosing whether to turn on the Fetch files feature.
Free up disk space, and then follow these steps to start syncing your OneDrive folder on the computer again:
