Why teams connect Dremio and Microsoft 365

Get the data locked inside Microsoft 365 into Dremio 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 Teams, Planner & To Do Tasks, Users, Groups from Microsoft 365 into tables in Dremio continuously, handling schema, rate limits, and retries. Because the sync is bi-directional, results computed in Dremio can also be written back into fields in Microsoft 365 where the tool can use them.

Common use cases

  • Mirror calendar events into scheduling or CRM tools so meetings appear on customer timelines.
  • Sync SharePoint lists with operational databases so business users edit in SharePoint while systems read SQL.
  • Sync curated Dremio views into an operational Postgres so applications get low-latency access to lakehouse data.
  • Reverse-ETL aggregates computed over lake data out to CRMs and finance tools for business users.

Cross-tool reporting

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

Where Microsoft 365 accepts updates: operational write-back

Segments, scores, or reference values computed in Dremio sync back onto records in Microsoft 365, putting analysis where the work happens.

History that outlives the tool

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

What you can sync between Dremio and Microsoft 365

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.

Dremio objects Microsoft 365 objects
Jobs Query execution records useful for monitoring sync workloads. SharePoint Sites & Lists List items read and written like lightweight database tables.
Sources Connected storage and database systems (S3, ADLS, relational databases) Dremio queries in place. Teams Team and membership data provisioned from upstream systems.
Physical datasets Tables and files promoted from sources; the raw data a sync ultimately reads. Planner & To Do Tasks Task items synced with project and work-management tools.
Virtual datasets (views) SQL views layering semantics over physical data; the preferred sync target for curated extracts. Users Entra ID user accounts synced with HR and identity systems.
Apache Iceberg tables Lakehouse tables supporting DML and snapshot metadata usable for incremental reads. Groups Microsoft 365 and security groups kept aligned with org structure and access rules.
Spaces and folders Namespaces that organize virtual datasets and govern access. Mail Messages Exchange Online messages read for logging, archiving, or activity capture.
