Hi David 

Thanks you for reply, are you sure about this? Windows and Samba SMB byte range locking feature doesn't allow this by locking regions of a single file ?

Even on pure Windows file servers you cannot effectively have simultaneous read/write for multiple users. I may have had 2 simultaneous users work one time for a few minutes. But it is not stable. So not even a microsoft server can do it.

Hello everyone 

I trying find what it happens on my Samba AD servers especially with shared spreadsheets, my personal opinion this feature on Excel is crap and unreliable but many people use it, how does Samba currently behave with this ? Is someone experienced any problem with this ? Frequently happens changes made by other user are lost the spreadsheet opens as read only , the shares are all using vfs_acl_xattr module to mimic NTFS permissions, clients are all windows machines versions 7 and 10 , i upgraded samba 4.3.11 to 4.5.7 but both have the same behavior.
