Why teams connect Intercom and Microsoft 365

Sync what happens in Microsoft 365 with the customer records in Intercom, in real time and in both directions.

The CRM is supposed to be the record of every customer relationship, but customer-relevant information also accumulates in the other tools a team runs. Whatever Microsoft 365 holds or produces that touches a customer, whether conversations, payments, replies, enriched data, or notes, the CRM only benefits if it arrives without someone copying it over.

Stacksync connects Teams, Planner & To Do Tasks, Users, Groups in Microsoft 365 to Contacts, Companies, Conversations, Tickets in Intercom with bi-directional, real-time sync. Activity and record changes in Microsoft 365 update the matching contact or account in Intercom, and CRM data flows the other way wherever Microsoft 365 can store and use it.

Common use cases

  • Sync SharePoint lists with operational databases so business users edit in SharePoint while systems read SQL.
  • Archive mail and file metadata into a warehouse for compliance and activity analytics.
  • Push product usage events from an application database into Intercom to trigger onboarding and retention messages
  • Mirror conversations and tickets into a warehouse for support analytics and SLA reporting

Where Microsoft 365 supplies contact or company data

Where Microsoft 365 processes payments

Where Microsoft 365 can store CRM context: fields kept current

Owner, lifecycle stage, or account details from Intercom sync into Microsoft 365, so people working there have the context without switching tools.
