With the recent update to our platform, Meeting Room Schedule now fully supports Microsoft Graph API connections for a smoother, more secure, and modern integration with Microsoft 365 calendars. This guide walks you through setting up your calendar type, choosing Microsoft Enterprise app registration – Client secret method, filtering resources, and pushing the calendar to your display device. This method uses an application registered in Microsoft Entra ID to authenticate with Microsoft Graph using a Client Secret. This option is suitable for companies with an internal IT team, Microsoft 365 administrator, or managed service provider who wants to control application access centrally. It can be a good fit for organizations managing multiple meeting room displays and preferring application-based authentication over individual account sign-ins. The Microsoft 365 administrator must provide the Application (Client) ID, Tenant ID and Client secret.

For other enterprise authorization scenario such as authentication with Microsoft Graph using a certificate, read here, or authentication with Microsoft account sign in, read here.
