Since only the owner of a given OneDrive (for Business) site has access to it by default, I would say this is the expected behavior. He can share the saved file with other users, or an admin can grant site-wide access to another person's OneDrive, if needed. But by default files stored in someone's OneDrive are private to this person only.
Unable to download ZIP attachments.

Receiving error while downloading the ZIP attachments received from external clients in OWA. If the ZIP file does get Saved to One drive, the other person trying to access the ZIP file receive access denied error. The other person needs to get access from that person who was able to save the ZIP file in his Onedrive. Is this an expected behavior?
