Hi,
thanks for the reply.
Are you using the new OneDrive sync client? Please first make sure you are using the new OneDrive sync client OneDrive.exe. Please download the
new OneDrive sync client and refer to
Sync files with the new OneDrive sync client in Windows.
Yes, Onedrive client version is 17.3.7131.1115.
- Is the user syncing his OneDrive or a SharePoint library?
Onedrive
- Please provide us any error message screenshots (English version please)
Translation:
"You now have two copies of a file. It was not possible to join the changes in XXX.docx, so we have created another copy of the file. Klick here to (message text cut, not possible to read further)"

Below you can see that the file, saved in Onedrive folder on C:, immediately is downoaded from Onedrive to the computer. This happens immediately after the saving in C:
Laddar ner = downloading.

This is the result:

- To check if the issue is related to his account, please try to sign in with another account to see if this account can reproduce the issue on this same computer.
The issue is not reproduced when signing in another account to the same computer, using the same copy of Word in the same Windows user account.
The isssue is partly reproduced when signing in the affected account to another computer (same version of Onedrive sync client). Files seem to sync fine, but we do get the red x on the Onedive icon. The icon turns green on restarting the PC. (In
this computer, for testing we have only synced one folder and the files that are saved outside folders. I have now started a 2 GB sync of folders corresponding with the user's own computer and will get back after testing this setup)
Additional info
it seems like that the issue only occurs if a file is saved in a subfolder to Onedrive folder in C:, that is like C:\Users\Name\Onedrive - business name\Subfolder\testdoc.docx
Sometimes, when Onedrive icon is red x, this sign appears. It happens in both tested computers, apparently randomly.
It says "This file is not connected to an application in order to perform the action. INstall an application och create an association in the Control panel object Standard applications if an application already is installed"

When this sign appears, Onedrive address in Windows explorer address bar is changed to this:

This is how the documents are saved:
