Microsoft 365 Copilot requires supported Microsoft 365 applications to provide integrated AI functionality in desktop Word, Excel, PowerPoint, and other Office applications.
The sales department already has Microsoft 365 E3 and Microsoft 365 Copilot licenses. Consequently, the primary issue is not the licensing configuration but the installed Office application version.
Option B is correct because deploying Microsoft 365 Apps provides the continuously updated desktop applications that support Copilot integration. Administrators must ensure that users are signed in with appropriately licensed Microsoft Entra accounts and that the applications receive supported feature updates.
Option A is incorrect because Office LTSC Professional Plus 2024 is a perpetual-license product that does not receive the continuously delivered Copilot capabilities provided through Microsoft 365 Apps.
Option C is incorrect because Microsoft 365 E5 is not required when users already have qualifying Microsoft 365 E3 licenses and Copilot licenses.
Option D is incorrect because Microsoft Graph connectors integrate external information sources with Microsoft 365 search and Copilot grounding. They do not enable Copilot inside unsupported desktop applications.
Option E is incorrect because participation in the Frontier program is not required to activate standard licensed Copilot functionality.
Therefore, Microsoft 365 Apps must be deployed to the devices.
