Final answer:
To protect Word and Excel documents on an on-premise file server, you can implement BitLocker encryption, use Azure Information Protection, or configure OneDrive for Business access.
Step-by-step explanation:
To allow users to protect Word and Excel documents on an on-premise file server, you can implement BitLocker encryption. BitLocker is a built-in Windows feature that encrypts entire drives, including the files stored within them. By encrypting the file server with BitLocker, only authorized users with the encryption key can access the documents.
Additionally, Azure Information Protection can be used to protect Word and Excel documents residing on the on-premise file server. Azure Information Protection provides classification, labeling, and protection features that help secure sensitive information.
Configuring OneDrive for Business access is another method to protect Word and Excel documents on an on-premise file server. By storing the documents in a user's OneDrive for Business account, Microsoft provides additional security features such as access controls, encryption, and multi-factor authentication.
