โ˜๏ธ

If OneDrive has stopped syncing, a reset is usually the quickest fix. Note: depending on how many files you have, resyncing can take a while and use significant bandwidth.

1

Close OneDrive

Right-click the OneDrive icon in the system tray and select Close OneDrive.

2

Run the reset command

Press Windows Key + R to open the Run dialog. Paste the following command and press Enter:

%localappdata%\Microsoft\OneDrive\onedrive.exe /reset

This resets OneDrive. If it doesn't reopen automatically, launch it from the Start menu.

3

If the reset doesn't work โ€” Relink your account

Right-click the OneDrive icon in the system tray and go to Settings. Click Unlink this PC, then sign back in to relink your account.

4

Last resort โ€” Reinstall OneDrive

Uninstall OneDrive from Settings > Apps, then reinstall it from office.com or the Microsoft Store.

โœ“

OneDrive syncing again

Your files will begin resyncing. Give it some time if you have a large number of files.

Common OneDrive error messages

  • "Files are too large to upload" โ€” ensure no files exceed the 250GB size limit
  • "You don't have permission to sync this library" โ€” check your SharePoint permissions with your admin
  • "A file or folder with this name already exists" โ€” rename the conflicting file or folder

Frequently asked questions

Why has OneDrive stopped syncing in Windows 11? +

OneDrive can stop syncing for several reasons including account sign-out, storage limits being reached, file name conflicts, proxy settings, or a corrupted sync state. Running the reset command resolves most cases.

How do I reset OneDrive without losing files? +

Press Windows Key + R and run %localappdata%\Microsoft\OneDrive\onedrive.exe /reset โ€” This resets the sync engine but does not delete any files. Your files remain on the server and will resync after the reset.

What does the OneDrive reset command do? +

The /reset command restarts the OneDrive sync engine and clears its internal state, forcing it to re-establish a fresh connection to your Microsoft 365 account and resync all files.

OneDrive says 'Files are too large to upload' โ€” what does this mean? +

Individual files in OneDrive cannot exceed 250GB. If a file exceeds this limit it will not sync. You will need to compress, split, or store it elsewhere.
