Yes, you can store and share Excel files using OneDrive for Business, specifically within the “My Files” section. Here’s what you need to know:

• Files created or uploaded using “+ Add New” on OneDrive, or shared via Microsoft Teams chat, are automatically saved in “My Files”.
• You can share files directly from “My Files” with others.

📁 Folder Sharing Limitations

Currently, there is no confirmed method to create a new folder that can be shared internally in your environment. As a workaround:

• Please create folders directly in OneDrive.
• Use file-level sharing options as needed until folder-level sharing becomes available.
