A user needs to access their work files from a personal device without storing a copy locally. Which Microsoft 365 app should they use?
OneDrive for Business allows files on demand, streaming from the cloud.
Why this answer
OneDrive for Business enables users to access work files from any device via the cloud, with the option to stream files on demand without downloading them locally. This is achieved through Files On-Demand, which uses placeholder files and syncs only metadata, ensuring no full copy is stored on the personal device unless explicitly made available offline.
Exam trap
The trap here is that candidates may confuse SharePoint's web-based access with the ability to prevent local storage, overlooking that OneDrive for Business is the only option with a dedicated Files On-Demand feature that explicitly avoids storing a full copy locally on personal devices.
How to eliminate wrong answers
Option A is wrong because Microsoft Outlook is an email and calendar client, not designed for file storage or remote access without local copies; it downloads attachments locally by default. Option C is wrong because Microsoft Teams primarily focuses on chat, meetings, and collaboration, and while it can access files from SharePoint or OneDrive, it does not provide a dedicated mechanism to prevent local storage of files on personal devices. Option D is wrong because Microsoft SharePoint is a web-based document management and collaboration platform that can be accessed via browser, but it does not natively offer a Files On-Demand feature to prevent local caching; files opened from SharePoint in a browser may still be cached locally by the browser or Office apps.
