Why teams connect Firebase and Microsoft 365
Mirror Microsoft 365's data into Firebase 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 Firebase.
Stacksync mirrors Mail Messages, Calendar Events, Contacts, OneDrive Files (driveItems) from Microsoft 365 into Authentication Users, Cloud Storage Objects, Cloud Functions Triggers, Firestore Collections in Firebase 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
- 01 Mirror calendar events into scheduling or CRM tools so meetings appear on customer timelines.
- 02 Sync SharePoint lists with operational databases so business users edit in SharePoint while systems read SQL.
- 03 Combine Firebase Authentication users with billing and CRM records into one customer table.
- 04 Replace one-off Cloud Functions export code with managed, continuous sync.
Common sync patterns
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 Firebase; 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 Firebase and Stacksync propagates the change into Microsoft 365, replacing custom integration code.
What you can sync between Firebase 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.
| Firebase objects | Microsoft 365 objects | How this pairing syncs | |
|---|---|---|---|
| Authentication Users User accounts read into CRMs and warehouses for customer records. | Contacts Personal and org contacts kept consistent with CRM contact records. | Authentication Users is specific to Firebase and Contacts to Microsoft 365 — each maps to any object or custom field on the other side. | |
| Cloud Storage Objects Files referenced from documents; usually synced as metadata plus URLs. | OneDrive Files (driveItems) File and folder metadata synced for document workflows and audits. | Cloud Storage Objects is specific to Firebase and OneDrive Files (driveItems) to Microsoft 365 — each maps to any object or custom field on the other side. | |
| Cloud Functions Triggers Server-side hooks that fire on document changes and can push updates outward. | SharePoint Sites & Lists List items read and written like lightweight database tables. | Cloud Functions Triggers is specific to Firebase and SharePoint Sites & Lists to Microsoft 365 — each maps to any object or custom field on the other side. | |
| Firestore Collections Top-level groupings of documents that a sync maps to tables or SaaS objects. | Teams Team and membership data provisioned from upstream systems. | Firestore Collections is specific to Firebase and Teams to Microsoft 365 — each maps to any object or custom field on the other side. | |
| Firestore Documents Schemaless JSON-like records, the primary unit synced to and from external systems. | Planner & To Do Tasks Task items synced with project and work-management tools. | Firestore Documents is specific to Firebase and Planner & To Do Tasks to Microsoft 365 — each maps to any object or custom field on the other side. | |
| Subcollections Nested collections under documents, typically flattened into related tables during sync. | Users Entra ID user accounts synced with HR and identity systems. | Subcollections is specific to Firebase and Users to Microsoft 365 — each maps to any object or custom field on the other side. |
How changes propagate between Firebase and Microsoft 365
Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.
Firebase Microsoft 365 Interval-based propagation
DetectionStacksync polls Firebase for changes on an incremental schedule, reading only records changed since the previous pass. Real-time snapshot listeners on Firestore queries and Cloud Functions triggers on document changes.
DeliveryEach detected change is written to Microsoft 365 through its API, with automatic retries and rate-limit backoff.
Microsoft 365 Firebase Sub-second propagation
DetectionMicrosoft 365 notifies Stacksync of record changes through webhook events. Graph change notifications (webhooks) plus delta queries for incremental sync.
DeliveryEach detected change is written to Firebase through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Firebase: Subject to Firestore's documented operation quotas and per-document write throughput limits.

FAQ
Firebase and Microsoft 365 integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Firebase and Microsoft 365: authenticate both systems, choose the objects to sync (such as Firebase's Authentication Users and Cloud Storage Objects), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Firebase and Microsoft 365 records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Firebase and Microsoft 365 connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Firebase–Microsoft 365 integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Firebase and Microsoft 365. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Firebase: Real-time snapshot listeners on Firestore queries and Cloud Functions triggers on document changes. On Microsoft 365: Graph change notifications (webhooks) plus delta queries for incremental sync. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
-
On the Microsoft 365 side: Mail Messages, Calendar Events, Contacts, OneDrive Files (driveItems), plus custom fields where Microsoft 365 exposes them. On the Firebase side: Authentication Users, Cloud Storage Objects, Cloud Functions Triggers, Firestore Collections. Stacksync auto-detects both schemas and converts types between the two systems.
