How to allow concurrent editing of word/ excel/ PowerPoint files on Windows file sharing in my office network

This issue happens because Microsoft Office locks files when they’re in use, preventing multiple users from editing at the same time. The best way to enable real-time collaboration is by using OneDrive or SharePoint, which allows multiple users to work on Word, Excel, and PowerPoint files simultaneously with AutoSave.

If you prefer to keep files on your local network, you can try enabling Excel’s Shared Workbook feature, though it has limitations and doesn’t work for Word or PowerPoint. Adjusting file sharing permissions may help, but Office will still lock files once they’re opened.

If real-time editing is a priority, Google Docs, OnlyOffice, or Zoho Docs could be good alternatives. Otherwise, moving files to OneDrive or SharePoint is the best long-term solution. Hope this helps!

Does Windows Server 2022/ 2025 Data Centre edition provide real time collaboration/ concurrent editing (through workspaces etc) by multiple users on Microsoft office documents hosted on it locally.

So for the sole purpose of having concurrent editing feature of office documents, can Windows Server 2022/ 2025 Data Centre edition become an alternative to using Sharepoint server hosted locally/ on premise.

Simultaneous editing will require that the files are stored in OneDrive or SharePoint, I believe. See Document collaboration and co-authoring - Microsoft Support.
