SharePoint Error: your file wasn't uploaded because your changes can't be merged

We are using SharePoint as our file server recently many of my user started to complaint they are not able to save the document online and all of them getting the similar error as below:

Due to this error they has to make a copy to the local desktop and replacing in the SharePoint directory. This is causing confusion among users that are trying to edit the same document because different versions or copies are having to be saved to SharePoint.

Hi @Fawell,

  • Make sure you and your colleagues using the latest version of office or at least same version of office installed in their pc.

  • If this excel file is password protected then this error is expected. Try to remove the password and see if this error gone away.

  • Delete the cache for the office upload center and check whether you can save or not.
    Click on Windows key> Enter Office Upload Center> Click on it to Open> Settings> Delete cached file> Ok.

  • Make sure you have not change the file or folder name. Renaming file or folder name can also cause this issue.



Hi @Fawell,

It is very common error in Microsoft office. I think you have missed one option in OneDrive client that isn’t been checked. You can open OneDrive Settings > Office > make sure “Use Office applications to sync files that I open” option is checked.


Even after following the above solution if you face the problem again please follow the below steps:

  1. Does the problem happen on other Office files, such as: Word document or excel file?

  2. Are the files opened by these users in the “checked out” state?

  3. Make sure you are using the latest version of Microsoft Office in your PC

  4. Go to uninstall programmers and run online repair for your Office application

If you still face the same problem please let me know to assist you furthur

Best regards,
