Hi @Anonymous ,
I couldn't reproduce this issue in my end. I enabled content approval and major/minor versions in a document library, then I synced the library to OneDrive. There is also a lock icon in status field. I can both open the word document in edit mode by the word application in SharePoint and OneDrive folder.
To narrow down your issue, let's verify the followings.
- As said in the article you post, have you checked the Draft Item Security settings in Version Settings?
when Draft Item Security is set to either Only users who can edit or Only users who can approve items in Version Settings of the library: For SharePoint document libraries, these items will be synchronized as read-only.
- Some others causes of this issue are listed in this article: SharePoint files open as read-only, please also to check them in your environment.
- You mentioned that some users ran into this issue. So, does this problem only happen to part of the users or all users? Is there any difference between them?
- Please guide the issue users to try to open the word documents on another computers and verify if the issue still persists.
- Which version of office the users are using? My test is based on Microsoft Office Professional Plus 2016 in Windows 10 and I will deploy an environment identical to yours to retest if it is needed.
