How the work unfolds

Discovery and scoping

Confirm the business processes to be automated, HubSpot objects involved, Outlook user groups, email logging rules, calendar synchronization requirements, approval scenarios, data retention expectations, and reporting needs. Final hourly / time-and-materials estimate and timeline are confirmed after this scope is approved.

Access and environment readiness

Validate Microsoft 365, Outlook, HubSpot, Power Automate, and any middleware requirements. Confirm administrator access, OAuth consent approach, HubSpot app connection approach, test accounts, API limits, and least-privilege permissions.

Solution design and field mapping

Design the integration architecture using Microsoft Graph API, HubSpot REST API, HubSpot Email Events API, HubSpot Marketing Events, Power Automate, or custom middleware as appropriate. Define field mappings, object relationships, workflow triggers, error handling, logging, and exception processes.

Connect HubSpot to Outlook

Connect HubSpot to Outlook using Microsoft Graph API and HubSpot REST API with OAuth 2.0 authentication, TLS 1.2+, and least-privilege API permissions.

Configure email and event logging

Configure logging of Outlook emails and events to HubSpot via Power Automate or custom middleware. Validate attachment to HubSpot Contacts, Companies, Deals, Tasks, Marketing Events, or Marketing Activities based on the approved scope.

Configure workflow triggers and actions

Configure triggers such as flagged emails creating HubSpot Tasks, calendar events syncing as Marketing Activities, follow-up reminders, SLA reminders, and campaign approval actions from Outlook activity.

Configure optional Outlook actions and approvals

Where included in scope, build actionable Outlook buttons such as "Log to HubSpot" or "Approve Campaign" and optional multi-step approval flows, such as Outlook replies feeding HubSpot approval processes.

Testing and remediation

Run functional testing with agreed test users and sample records. Validate authentication, field mappings, duplicate handling, workflow triggers, user experience, error notifications, and security configuration. Remediate defects identified during testing.

User acceptance and production deployment

Support client user acceptance testing, obtain approval to proceed, deploy the integration to production, and validate core scenarios after deployment.

Handover, documentation, and support transition

Provide configuration documentation, operational notes, known limitations, and support handover. Transition the integration into monitoring, maintenance, support, and optimization activities only where purchased as an optional extra-cost add-on or otherwise included in a separate agreed scope.
