Is there a way to acces the windows native networking feature over the internet

Question

In my company currently we use an excel sheet to provide new item numbers for new products. The file is currently available on network location accessed by all of us. We access that sheet one person at a time and for others it just opens read only. Now the problem is that our sister company people also want to use that sheet so we have synced that folder where the file is with onedrive to the other company's pc. The work goes flawlessly but the caveat is that people in other company don't get notification when here we are using that file (Obviously because onedrive does not make the read oly when people at our side is working on it) so onedrive makes two copies in the event of a conflict in data say people from there and here have done entry in same row. Is there a way to access that file the same way as we do nagively in womdows network location so that when somebody using that file it opens read only for other company's people as well?
