Question

A marketing manager at your company has a Microsoft 365 Copilot license. She asks you why, when she uses Copilot Chat in 'Web' mode, it does not reference her recent internal campaign documents, but when she toggles to 'Work' mode it can summarize those same files. What is the correct explanation of this difference?

Accepted Answer

Web mode grounds responses only in public internet content, while Work mode grounds responses in organizational data through Microsoft Graph.

Answer

Web mode uses a smaller, less capable language model that cannot process document attachments.

Answer

Work mode requires a separate Copilot Studio agent to be published before it can access any files.

Answer

Web mode is only available to users without a Microsoft 365 Copilot license, so it intentionally blocks all file access.
