Hi,
Did you like share us the screenshot of the error message? I suppose that you get the error message like this: "The document is locked for editing by another user." Am I right? If yes, please try the method:
Turn off the Preview Pane, Details Pane and pop ups that show information about file and desktop items. In a Windows Explorer window, do the following:
1. Right click on the Start Button.
2. Click 'Open Windows Explorer'.
3. At the top left click Organize > Layout
4. Uncheck Details Pane and Preview Pane.
5. On a Windows menu, click on Tools > Folder Options. In the box that opens up, click on the View tab. Scroll down the list to
Show pop-up description for folder and desktop items and clear the checkbox and then click OK.
If I misunderstood something, please feel free let me know.
Regards,
