Here are some error messages you might receive when you try to upload files from the OneDrive website, along with possible solutions. For help with files not syncing, see how to fix OneDrive sync problems for: Windows 8.1 or Windows RT 8.1, Windows 10, Windows 7 and Windows Vista, or Mac.
OneDrive can't upload this file
You might get this message for one of these reasons:
There was a problem with OneDrive. Try to upload the file again.
The connection to OneDrive was lost during the file transfer, or you weren't signed in to OneDrive. Sign in to OneDrive with your Microsoft account, and then try to upload the file again.
You don't have permission to access the file. If the file is on a server, make sure you can open the file, and then try to upload it again. For more info about getting permission to access the file, contact your network administrator.
You don't have permission to upload the file to the folder that you selected. Select a folder that you have permission to edit, and then try to upload the file again.
A file with this name already exists
Click Replace to replace the existing file, or Keep both to rename the file you're uploading.
Note: If a file doesn't have an extension, it can't be uploaded to a location that has a folder with the same name.
Sorry, OneDrive can't upload folders or empty files
To upload files to a new folder in OneDrive, first create the folder, and then upload the files to it. Files that are 0 bytes in size can't be uploaded from the OneDrive website.
Tip: If you use Windows 10, Windows 8.1 or Windows RT 8.1, or have the free OneDrive desktop app installed, you can upload entire folders to OneDrive without even having to go to the OneDrive website.
This file is too big
If you use Internet Explorer 10 or a recent version of other popular web browsers, you can upload files to OneDrive that are up to 10 GB in size. If you use an older web browser, you can't upload files larger than 300 MB.
Tip: You can upload files up to 10 GB in size if you use Windows 10 or Windows 8.1, or install the free OneDrive desktop app.
You're out of storage
A file won't upload if it doesn't fit in your available storage space. To see how much space you have remaining or get more storage, go to the Storage page.
OneDrive can't upload this file to this location
The full path (including the file name) is too long. The path must contain fewer than 442 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, and then try to upload the file again.
This file contains restricted characters
The file name contains characters that aren't allowed. 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
OneDrive can't find this file
The file might have been moved, renamed, or deleted before you tried to upload it. Locate the file, and then try to upload it again.
OneDrive can't access this file
The file might be open in another program. Save any changes to the file, close the program, and then try to upload the file again.
If the file is on a removable media device, such as a CD or a USB flash drive, the file might not be available. Make sure that the removable media device is correctly connected to the computer, and then try to upload the file again.
