Why teams connect InterSystems IRIS and Microsoft 365

Mirror Microsoft 365's data into InterSystems IRIS 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 InterSystems IRIS.

Stacksync mirrors Planner & To Do Tasks, Users, Groups, Mail Messages from Microsoft 365 into Stored Procedures, Tables, Views, Schemas in InterSystems IRIS 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

  • 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.
  • Write enriched or corrected records from SaaS apps back into IRIS tables for on-platform processing
  • Replicate IRIS tables to Postgres so application teams can build against a familiar database

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 InterSystems IRIS; 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 InterSystems IRIS and Stacksync propagates the change into Microsoft 365, replacing custom integration code.

What you can sync between InterSystems IRIS 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.

InterSystems IRIS objects Microsoft 365 objects
Views SQL views expose curated slices of data for outbound replication. Contacts Personal and org contacts kept consistent with CRM contact records.
Schemas Schema organization scopes which tables a sync connection can see. OneDrive Files (driveItems) File and folder metadata synced for document workflows and audits.
Persistent Classes Object-model classes project to tables, so class data is reachable through SQL. SharePoint Sites & Lists List items read and written like lightweight database tables.
Globals The underlying multidimensional storage; typically accessed indirectly via SQL or objects in syncs. Teams Team and membership data provisioned from upstream systems.
Namespaces Namespaces partition databases and determine the connection context for integrations. Planner & To Do Tasks Task items synced with project and work-management tools.
Stored Procedures Server-side logic callable over SQL supports controlled writes and transformations. Users Entra ID user accounts synced with HR and identity systems.
