Two-way sync
Changes in Microsoft 365 or Oracle DB instantly reflect in both systems. No stale data, no manual imports.
Keep Microsoft 365 and Oracle DB in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
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 Oracle DB.
Stacksync mirrors Groups, Mail Messages, Calendar Events, Contacts from Microsoft 365 into Schemas, Sequences, PL/SQL procedures and packages, Partitions in Oracle DB 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.
Write to the synced tables in Oracle DB and Stacksync propagates the change into Microsoft 365, replacing custom integration code.
Updates in Microsoft 365 arrive as row changes in Oracle DB, so triggers, jobs, and services can respond in near real time.
Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.
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 | Oracle DB objects | |
|---|---|---|
| Users Entra ID user accounts synced with HR and identity systems. | Materialized views Precomputed results occasionally used as stable replication sources | |
| Groups Microsoft 365 and security groups kept aligned with org structure and access rules. | Schemas Per-user namespaces that scope sync permissions and object visibility | |
| Mail Messages Exchange Online messages read for logging, archiving, or activity capture. | Sequences Key generators to respect when external systems insert rows | |
| Calendar Events Events synced with scheduling tools and CRMs for meeting visibility. | PL/SQL procedures and packages In-database logic that can consume or transform synced data | |
| Contacts Personal and org contacts kept consistent with CRM contact records. | Partitions Physical subdivisions relevant when replicating high-volume tables | |
| OneDrive Files (driveItems) File and folder metadata synced for document workflows and audits. | JSON columns Document data stored in the converged engine and synced alongside relational rows |
Real-time sync, workflow automation, event queues, EDI, and monitoring, for every Microsoft 365–Oracle DB connection.
Changes in Microsoft 365 or Oracle DB instantly reflect in both systems. No stale data, no manual imports.
Trigger automated workflows whenever Microsoft 365 or Oracle DB data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.
Handle millions of events per minute without losing a single Microsoft 365 or Oracle DB record.
Track your Microsoft 365 ⇄ Oracle DB sync health, view errors, and replay failed events in one click.
Transform legacy EDI complexity into simple database interactions between Microsoft 365 and Oracle DB.
Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.
Authenticate Microsoft 365 and Oracle DB with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.
Pick the Microsoft 365 and Oracle DB objects to sync — Stacksync auto-detects both schemas, including custom fields where the platform exposes them. Sync to existing tables, or let Stacksync create new ones with ideal data types.
Fields map automatically even when names and types differ. Stacksync handles transformation and type casting for you, zero configuration required.
Yes. Stacksync provides a managed, real-time two-way integration between Microsoft 365 and Oracle DB: authenticate both systems, choose the objects to sync (such as Microsoft 365's Users and Groups), map fields visually, and changes propagate both ways in milliseconds — no code required.
Change detection on Microsoft 365: Graph change notifications (webhooks) plus delta queries for incremental sync. On Oracle DB: Log-based CDC from redo logs via LogMiner or GoldenGate, or trigger and timestamp polling. 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: Groups, Mail Messages, Calendar Events, Contacts, plus custom fields where Microsoft 365 exposes them. On the Oracle DB side: Schemas, Sequences, PL/SQL procedures and packages, Partitions. Stacksync auto-detects both schemas and converts types between the two systems.
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
Common patterns for Microsoft 365 and Oracle DB: Automate Microsoft 365 from your codebase; React to changes as they happen; One integration pattern for the whole stack. Write to the synced tables in Oracle DB and Stacksync propagates the change into Microsoft 365, replacing custom integration code.
Microsoft 365: REST API (Microsoft Graph). Authentication: OAuth 2.0 via Microsoft Entra ID, with delegated or application permissions. Oracle DB: SQL wire protocol (Oracle Net) via JDBC, ODBC, and native OCI drivers. Authentication: Database username and password; wallets, Kerberos, and directory-based authentication in enterprise setups. Stacksync manages authentication, retries, and rate limits on both sides.
