Quick Start

import asyncio
from evolvishub_outlook_ingestor import EmailIngestor, ingest_emails_simple

# Simple usage - minimal configuration
async def simple_example():
    result = await ingest_emails_simple(
        client_id="your-client-id",
        client_secret="your-client-secret",
        tenant_id="your-tenant-id",
        output_format="json"
    )
    print(f"Processed {result['processed_emails']} emails")

# Advanced usage - full control
