Hello,
Thanks for your update. Typically, when you share your files in Excel online, and by default anyone in your organization can use the link to open and edit the workbook. If you want to adjust who can use the link and what they can do with the link, select [People in your organization with the link can edit, select the options you want in the Link Settings dialog, and then select Apply ". In this way, these unknown people can't do anything about it either.
