1. Restart your computer and then try signing in to OneDrive again

Restart your computer. Sign in to OneDrive. Check the OneDrive status. If the OneDrive status is "Connected," then the problem is with the computer rather than with OneDrive. If the OneDrive status is "Offline," then the problem is with OneDrive. If the OneDrive status is "Error," then the problem is with OneDrive. If the OneDrive status is "Unknown," then the problem is with OneDrive or with the computer. Try troubleshooting the problem.

2. Check to see if there's an update for the OneDrive app

  1. Open the OneDrive app.
  2. On the main menu, click Settings.
  3. Under App updates, click Check for updates.
  4. If there's an update available, the app will check for and install it.
  5. If there's an update available, the app will tell you how to install it.
  6. If there's an update available, the app will tell you how to download and install it.
  7. If there's an update available, the app will ask you to install it.
  8. If you installed the update, the app will update itself.

3. Try signing in to OneDrive from a different browser

  1. Open a different browser and sign in to OneDrive.
  2. Click on the three lines in the top left corner of the screen.
  3. Select "Settings."
  4. Under "General," click on "Sign in."
  5. Enter your credentials and click on "Sign in."
  6. If you are having trouble signing in, try resetting your password.
  7. If you still cannot sign in, please Contact Us.

4. Make sure that the file you're trying to sync doesn't exceed the file size limit of 20 GB

  1. Open onedrive and sign in.
  2. Under the "Files" tab, select the file you want to sync.
  3. On the right, under the "File size" heading, click "Get info."
  4. On the right, under the "Details" tab, click "Size."
  5. The file size limit is 20 GB. If the file size is greater than 20 GB, onedrive will give you an error code 43. To fix this, you'll need to reduce the file size.
  6. To reduce the file size, you can either: a. Click the "Save" button to save the file to your computer. b. Click the "Download" button to save the file to the cloud. c. Click the "Less" button to reduce the file size by 10%. d. Click the "More" button to reduce the file size by 50%. e. Click the "All" button to reduce the file size by 100%. f. Click the "Compress" button to reduce the file size by 50%. g. Click the "Create archive" button to create an archive of the file. h. Click the "Delete" button to delete the file.
  7. If you need to sync the file again in the future, you can re-download it from the cloud or save it to your computer.

If the answers above didn't work then you should also try:

  1. Check the status of the OneDrive service and make sure it's running.
  2. Try uninstalling and then reinstalling the OneDrive app.
