It is important to know who you are sharing the folder with on OneDrive, as it allows you to control who has access to sensitive information.

Before sharing a folder or file, consider the following:

1. Know the recipient: Make sure that you are sharing the folder or file with the correct person or group. Double-check the email address of the recipient to ensure that you are sharing the folder or file with the right person.
2. Think about the level of access: Consider the level of access you want to give to the recipient. If the recipient only needs to view the folder or file, give them "View" access. If the recipient needs to make changes to the folder or file, give them "Edit" access.
3. Review company policy: Before sharing a folder or file, review your company's data security policies. Make sure that you are not violating any policies by sharing the folder or file with a specific person or group.
4. Keep track of shared folders: Keep track of the folders and files that you have shared, and who they have been shared with. This will help you monitor who has access to sensitive information and make changes to access permissions as needed.
5. Revoke access when necessary: If you need to revoke access to a folder or file, you can do so by going to the share box and clicking on the "Stop sharing" button.

It's very important to be aware of the company's data security policies and comply with them when sharing a folder or file on OneDrive. It's also important to keep track of who has access to the shared folder or file, and revoke access if necessary.

 When it comes to sharing files and folders on OneDrive, there is a difference between sharing and giving access:
