Solution for all OneDrive Sync Issues

#1. Check OneDrive App Status

Before troubleshooting first verify if your OneDrive is running or not. If it is not running, search for the OneDrive App and start it. Also make sure that your OneDrive app is enabled to auto-start when your PC boots(this can be configured from task manager > startup). After you start OneDrive app, your OneDrive files should start syncing

#2. File Format and Size

File format and File sizes can also be a reason why your OneDrive is not syncing or having sync problem. To verify whether you are using the correct and allowed file formats please check this Microsoft document and verify your file extension. If Microsoft does not allow the file type which you are trying to sync then, it is not possible to sync that particular document. One such example is .pst files. However as a work around, you can manually upload the .pst file through OneDrive web app.

Now regarding File size limitation, as per March 2021, Microsoft has increased the file size limit to 250GB for a single file. So for most of the users, file size should not be an issue while syncing. But still, verify your file size as well.
To know all restrictions of OneDrive check this Microsoft document.

#3. Verify the path for your OneDrive file

Syncing apps such such as OneDrive and SharePoint do not like long paths for files. As of Oct 2021, the limitation for OneDrive / SharePoint local file path is 255 characters (including file name). So verify if your file-path is too long. Try renaming it and make it shorter and check if it resolves the OneDrive not syncing problem(you may need to kick start the sync after renaming, more on the kick start process below).

#4. Kick-start OneDrive to resolve sync problems

Some times even after doing some changes OneDrive status do not change. In such cases, you need to kick start you OneDrive by either by pausing and resuming syncing or Quit and restart OneDrive app. Doing so will kick start your OneDrive sync process and may help to resolve your OneDrive not syncing problem or any OneDrive sync related errors.

#5. Move the affected file outside of OneDrive folder and then move it back

The most common / easiest method to troubleshoot OneDrive not syncing errors is by just moving the affected file out side of OneDrive and then moving it back to OneDrive.
Some time OneDrive has corrupt cache/configuration files which do not allow to sync a local file. In such scenarios

  1. First try to move the document from your OneDrive folder to a non-syncing folder
  2. Then wait for the move to complete
  3. Wait for few minutes
  4. Move the file back to OneDrive folder
  5. Kick-start OneDrive sync as mentioned in the above process(#4).

If you are unable to move your OneDrive file and receiving an error (0x80071129 – The tag present in the reparse point buffer is invalid) then, follow this document to fix the 0x80071129 error.

#6. Reset OneDrive

Resetting OneDrive can also help you to resolve your OneDrive sync related issues. A common misconception is that resetting OneDrive is going to remove / delete your OneDrive files but that is not true(as of Oct 2021). To reset your OneDrive for not syncing problems type the below command in your command prompt.
%localappdata%\Microsoft\OneDrive\onedrive.exe /reset
If the above code is not working, check this Microsoft document to properly reset your OneDrive.

To verify this check if you are able to ping the OneDrive server from your machine, if you are unable to ping the the OneDrive not syncing error is related to any of the above. In such case, contact your company IT or check your settings.
