Welcome to the Outlook integration docs. Once you connect your Microsoft account to Reasoning Stack, your AI agents and workflows can use the following tools to send emails, manage contacts, handle calendar events, and automate Outlook operations programmatically.
Before accessing any Outlook tools, connect your Microsoft account via the App Connection page. Without this, tool calls will fail due to missing authorization.
