Why teams connect Elasticsearch and Microsoft 365
Mirror Microsoft 365's data into Elasticsearch 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 Elasticsearch.
Stacksync mirrors Mail Messages, Calendar Events, Contacts, OneDrive Files (driveItems) from Microsoft 365 into Data streams, Ingest pipelines, Index templates, Indices in Elasticsearch 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
- Sync SharePoint lists with operational databases so business users edit in SharePoint while systems read SQL.
- Archive mail and file metadata into a warehouse for compliance and activity analytics.
- Feed enriched customer records into an index used for vector or hybrid search in AI applications.
- Sync CRM accounts and contacts into an Elasticsearch index to power internal search across customer records.
React to changes as they happen
Updates in Microsoft 365 arrive as row changes in Elasticsearch, so triggers, jobs, and services can respond in near real time.
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 Elasticsearch; join them, index them, and use them in application logic without touching the vendor API.
What you can sync between Elasticsearch 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.
| Elasticsearch objects | Microsoft 365 objects | |
|---|---|---|
| Index templates Reusable settings and mappings applied automatically to new indices a sync creates. | Groups Microsoft 365 and security groups kept aligned with org structure and access rules. | |
| Indices Target containers for synced records; each holds a table-like collection of JSON documents. | Mail Messages Exchange Online messages read for logging, archiving, or activity capture. | |
| Documents The unit of sync; JSON records created, updated, and deleted by _id. | Calendar Events Events synced with scheduling tools and CRMs for meeting visibility. | |
| Index mappings Field type definitions that determine how synced fields are indexed and queried. | Contacts Personal and org contacts kept consistent with CRM contact records. | |
| Aliases Stable read/write names that let a sync cut over between index versions without downtime. | OneDrive Files (driveItems) File and folder metadata synced for document workflows and audits. | |
| Data streams Append-only targets for time-series or event data pushed from source systems. | SharePoint Sites & Lists List items read and written like lightweight database tables. |

How the Elasticsearch and Microsoft 365 connectors work
Elasticsearch
- Integration surface
- REST API (JSON over HTTP)
- Authentication
- API keys or basic authentication; Elastic Cloud also issues service account tokens
- Change detection
- Polling on timestamp or sequence fields; Elasticsearch does not expose a native change feed or webhooks
- Capabilities
- read · write
- Rate limits
- No fixed request quota; throughput is bounded by cluster sizing, thread pools, and bulk queue capacity
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

FAQ
Elasticsearch and Microsoft 365 integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Elasticsearch and Microsoft 365: authenticate both systems, choose the objects to sync (such as Elasticsearch's Index templates and Indices), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Elasticsearch: REST API (JSON over HTTP). Authentication: API keys or basic authentication; Elastic Cloud also issues service account tokens. Microsoft 365: REST API (Microsoft Graph). Authentication: OAuth 2.0 via Microsoft Entra ID, with delegated or application permissions. Stacksync manages authentication, retries, and rate limits on both sides.
-
Microsoft 365: Access is scoped per permission via Entra ID admin consent, so an integration only sees the workloads it was granted. Elasticsearch: Optimistic concurrency uses _seq_no and _primary_term instead of row locks, which matters when two writers touch the same document. Stacksync's field mapping accounts for these differences between Elasticsearch and Microsoft 365 without custom code.
-
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 Elasticsearch 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 Elasticsearch and Microsoft 365 connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Elasticsearch–Microsoft 365 integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Elasticsearch and Microsoft 365. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
