N8N Workflow for O365 Outlook - Project Proposal

poject on Upwork

Proposed Approach

I've developed a comprehensive n8n workflow solution that precisely meets your requirements for importing contacts from MySQL to multiple Microsoft 365 Outlook mailboxes:

Core Functionality

• Extracts contact data from MySQL database using optimized queries
• Synchronizes contacts to multiple Outlook mailboxes simultaneously
• Prevents duplicates through intelligent comparison logic
• Operates on both scheduled intervals and on-demand triggers

Authentication & Data Handling Strategy

• Authentication: Implements OAuth 2.0 for secure Microsoft Graph API access
• Data Flow:
  1. MySQL extraction with pagination for large datasets
  2. Contact normalization and validation pre-processing
  3. Existing contact comparison via Microsoft Graph API
  4. Batch processing for new contact creation

API Limit Handling & Performance Optimization

• Batch Processing: Contacts are processed in configurable batches (20 contacts per batch)
• Rate Limiting: Implements exponential backoff algorithm to respect API constraints
• Performance Monitoring: Two dedicated logging tables track execution metrics:
  • Contact Sync Logs for overall performance tracking
  • Contact Sync Errors for detailed error information
• Error Rate Monitoring: Calculates failure percentages with configurable threshold alerts

Error Handling & Logging

• Comprehensive Error Tracking: Records all sync attempts with detailed error information
• Email Notifications: Automated alerts when error rates exceed defined thresholds
• Recovery Mechanisms: Failed contacts can be automatically reprocessed in subsequent runs
• Logging Database: Two MySQL tables provide detailed execution history and troubleshooting data

Relevant Experience

• 5+ years developing systems.
• +2 years work with n8n and automation.
• Extensive experience with Microsoft Graph API, including contact management endpoints
• Deep knowledge of MySQL optimization for large dataset processing
• Successfully delivered similar contact synchronization solutions for enterprise clients

Deliverables

1. Complete n8n Workflow: Fully functional, production-ready configuration
2. Documentation:
   • Installation and configuration guide
   • Database schema for logging tables
   • Troubleshooting and maintenance procedures
3. Initial Deployment Support:
   • Assistance with credential setup
   • Configuration fine-tuning
   • Performance testing

I'm available to start immediately and can provide references from similar projects upon request.
