Why teams connect Microsoft 365 and Neo4j

Mirror Microsoft 365's data into Neo4j so your own code can read and write it like any other table, with changes flowing both ways in seconds.

Engineers integrate with tools like Microsoft 365 through APIs, which means auth, pagination, rate limits, webhooks, and retry logic, all maintained forever and all different for every tool. Meanwhile the data would be trivial to use if it simply lived in Neo4j.

Stacksync mirrors Calendar Events, Contacts, OneDrive Files (driveItems), SharePoint Sites & Lists from Microsoft 365 into Databases, Users & Roles, Nodes, Relationships in Neo4j and keeps both sides in sync in real time. Your services query the database directly, and inserts or updates your code makes flow back into Microsoft 365, so the tool and the database never disagree.

Common use cases

  • Sync employee records from an HR system into Entra ID users and group memberships.
  • Mirror calendar events into scheduling or CRM tools so meetings appear on customer timelines.
  • Feed identity and access data into a graph for entitlement and blast-radius analysis.
  • Write computed relationship scores (fraud, influence, similarity) back to operational systems.

One integration pattern for the whole stack

Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.

Read Microsoft 365 with a query

Records from Microsoft 365 are ordinary rows in Neo4j; join them, index them, and use them in application logic without touching the vendor API.

Automate Microsoft 365 from your codebase

Write to the synced tables in Neo4j and Stacksync propagates the change into Microsoft 365, replacing custom integration code.

What you can sync between Microsoft 365 and Neo4j

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Microsoft 365 objects Neo4j objects
Contacts Personal and org contacts kept consistent with CRM contact records. Users & Roles Security principals controlling what an integration credential can query or modify.
OneDrive Files (driveItems) File and folder metadata synced for document workflows and audits. Nodes Entity records (customers, products, accounts) written from source systems as labeled nodes.
SharePoint Sites & Lists List items read and written like lightweight database tables. Relationships Typed, directed edges that carry the connections syncs exist to model.
Teams Team and membership data provisioned from upstream systems. Properties Key-value attributes on both nodes and relationships, mapped from source fields.
Planner & To Do Tasks Task items synced with project and work-management tools. Labels Node type markers used to map source tables or objects onto the graph.
Users Entra ID user accounts synced with HR and identity systems. Indexes & Constraints Uniqueness constraints and indexes that make MERGE-based upserts reliable and fast.
