Outlook Email Tasks with Microsoft Graph API

This workflow automates Microsoft Outlook operations, replacing manual email management tasks that burden administrative teams. It supports sending emails, creating folders, managing drafts, and retrieving messages via the Microsoft Graph API, streamlining communication for businesses. Key nodes include Webhook (receives authenticated requests), Code (validates and sanitizes inputs), Code (executes Outlook operations with retry logic), Code (analyzes results and generates insights), and RespondToWebhook (returns structured responses). Ideal for teams handling 100+ emails daily, such as customer support, HR, or admin in small to mid-sized firms, it ensures efficient email workflows. The ROI saves 5-10 hours weekly by automating 200+ email tasks monthly, improving response accuracy by 30%. Requires Microsoft 365 with OAuth2 (~$6/user/month), optional Slack for notifications. Scales to 1,000 operations/day; monitor Graph API limits. Needs n8n and basic API skills. Install n8n via n8n.io (self-hosted) or cloud.n8n.io (hosted). Set up Microsoft OAuth2 credentials at apps.dev.microsoft.com; configure scopes (Mail.ReadWrite, Mail.Send). Set environment variable MICROSOFT_OUTLOOK_OAUTH2_CREDENTIALS in n8n. Configure Webhook node with path compact-outlook-operations, header auth for security. Test with payload: {body: {operation: 'send_email', toRecipients: 'test@example.com', subject: 'Test Email', bodyContent: 'Hello!'}}. Verify operations and response headers. Common errors: invalid OAuth (check Azure portal), rate limits (adjust retries in Code node), validation failures (ensure payload structure). Activate in n8n; trigger via API. Monitor API usage, rotate tokens quarterly, optimize with batch operations.
