Requesting license details required to explore https://learn.microsoft.com/en-us/microsoft-agent-365/mcp-server-reference/mail

Hi Team, we’re trying to explore the calendar, outlook and email tools provided by Microsoft Graph MCP Server as per - https://learn.microsoft.com/en-us/microsoft-agent-365/mcp-server-reference/mail, but it looks like we need a Front Tier program license. We’re not sure which license is required, and we already have an Exchange Online plan. Could you please guide us on what license we need to use?

    Microsoft Graph MCP Server for Enterprise does not require a separate or special “Front Tier program” license.

    From a licensing perspective:

    1. There is no additional cost or separate license required specifically to enable or use the Microsoft MCP Server for Enterprise.
    2. The MCP Server for Enterprise is focused on Microsoft Entra identity and directory read-only scenarios (users, groups, applications, devices, and administrative reporting). Calendar and Outlook mailbox data are not listed as in-scope resources in the current preview description.
    3. Access to any underlying data always requires that the tenant and users already have the appropriate licenses for that data (for example, the relevant Microsoft 365/Exchange Online licenses for mailbox and calendar features). Those product licenses govern whether the data exists and is accessible; the MCP server itself does not add an extra licensing layer.

    Given the current documented scope, the Microsoft Graph MCP Server for Enterprise preview is not positioned as a Calendar/Outlook mailbox MCP server; it is centered on Microsoft Entra identity and directory insights. Existing Exchange Online plans and Outlook feature licensing continue to apply for Exchange/Outlook capabilities, but they are separate from the MCP Server for Enterprise enablement.
