Why teams connect Microsoft 365 and Snowflake

Get the data locked inside Microsoft 365 into Snowflake as live tables, and send results back where Microsoft 365 can use them, without writing a pipeline.

Whatever Microsoft 365 is used for, it accumulates data the rest of the company wants to analyze, and that data usually sits behind an API rather than in the warehouse. Building and babysitting an extraction pipeline is the tax most teams pay for it.

Stacksync syncs Planner & To Do Tasks, Users, Groups, Mail Messages from Microsoft 365 into tables in Snowflake continuously, handling schema, rate limits, and retries. Because the sync is bi-directional, results computed in Snowflake can also be written back into fields in Microsoft 365 where the tool can use them.

Common use cases

  • Keep CRM contacts and Microsoft 365 contacts aligned in both directions.
  • Sync employee records from an HR system into Entra ID users and group memberships.
  • Keep a customer 360 table aligned with its source systems in both directions instead of one-way reverse ETL
  • Push product usage aggregates from Snowflake into sales and success tools for account prioritization

History that outlives the tool

A continuously synced copy in Snowflake preserves a queryable record even as data ages out of Microsoft 365 or gets changed inside it.

Analytics on Microsoft 365's data

Records and events from Microsoft 365 land in Snowflake as queryable tables, current within seconds and ready to join with the rest of the warehouse.

Cross-tool reporting

Combine Microsoft 365's data with data from every other synced system to answer questions no single tool can.

What you can sync between Microsoft 365 and Snowflake

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 Snowflake objects
Calendar Events Events synced with scheduling tools and CRMs for meeting visibility. Tasks Scheduled SQL used to transform synced data after it lands.
Contacts Personal and org contacts kept consistent with CRM contact records. VARIANT Columns Semi-structured JSON payloads stored alongside relational columns.
OneDrive Files (driveItems) File and folder metadata synced for document workflows and audits. Virtual Warehouses The compute a sync's queries run on, sized independently of storage.
SharePoint Sites & Lists List items read and written like lightweight database tables. Databases Top-level containers that scope which data a sync can touch.
Teams Team and membership data provisioned from upstream systems. Schemas Namespaces within a database used to organize synced tables.
Planner & To Do Tasks Task items synced with project and work-management tools. Tables The main landing and activation target for synced records.

How the Microsoft 365 and Snowflake connectors work

Microsoft 365

Integration surface
REST API (Microsoft Graph)
Authentication
OAuth 2.0 via Microsoft Entra ID, with delegated or application permissions
Change detection
Graph change notifications (webhooks) plus delta queries for incremental sync
Capabilities
read · write · webhooks

Snowflake

Integration surface
SQL via JDBC/ODBC and native drivers, plus the Snowflake SQL REST API
Authentication
Dedicated Snowflake service user + role with RSA key-pair authentication (Stacksync-provided public key), created via a setup script requiring SECURITY_ADMIN and ACCOUNTADMIN roles
Change detection
Not explicitly stated; the setup script grants "create stream" on synced schemas (Snowflake streams), but the docs do not name the change-capture mechanism
Capabilities
read · write · CDC
Rate limits
No conventional API rate limits; cost and throughput are governed by virtual warehouse size and running time
