Two-way sync
Changes in Microsoft 365 or Seismic instantly reflect in both systems. No stale data, no manual imports.
Keep Microsoft 365 and Seismic in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
The CRM is supposed to be the record of every customer relationship, but customer-relevant information also accumulates in the other tools a team runs. Whatever Microsoft 365 holds or produces that touches a customer, whether conversations, payments, replies, enriched data, or notes, the CRM only benefits if it arrives without someone copying it over.
Stacksync connects Users, Groups, Mail Messages, Calendar Events in Microsoft 365 to Library Content, Content Versions, Users, User Groups in Seismic with bi-directional, real-time sync. Activity and record changes in Microsoft 365 update the matching contact or account in Seismic, and CRM data flows the other way wherever Microsoft 365 can store and use it.
Enriched fields land directly on records in Seismic, and refreshes keep them from going stale.
Charges, refunds, and subscription changes appear on the account in Seismic, so revenue context lives with the relationship.
Owner, lifecycle stage, or account details from Seismic sync into Microsoft 365, so people working there have the context without switching tools.
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 | Seismic objects | How this pairing syncs | |
|---|---|---|---|
| Users Entra ID user accounts synced with HR and identity systems. | Users User records managed through SCIM 2.0 and legacy user endpoints; created, updated, and deactivated for provisioning sync. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Teams Team and membership data provisioned from upstream systems. | Teamsites Tenant-scoped workspace partitions organizing Library content, permissions, and config; scoped by teamSiteId on most content calls. | Teams is specific to Microsoft 365 and Teamsites to Seismic — each maps to any object or custom field on the other side. | |
| Planner & To Do Tasks Task items synced with project and work-management tools. | LiveSend Links Trackable content-share links created via the engagement API; their open and view engagement is read back through Reporting. | Planner & To Do Tasks is specific to Microsoft 365 and LiveSend Links to Seismic — each maps to any object or custom field on the other side. | |
| Groups Microsoft 365 and security groups kept aligned with org structure and access rules. | Digital Sales Rooms Buyer-facing microsites (DSRs); lifecycle and content-change events surface via webhooks, currently marked Early Access. | Groups is specific to Microsoft 365 and Digital Sales Rooms to Seismic — each maps to any object or custom field on the other side. | |
| Mail Messages Exchange Online messages read for logging, archiving, or activity capture. | Reporting Activities Content-interaction, engagement, and usage analytics extracted read-only through the ETL-oriented Reporting API v2 for a warehouse. | Mail Messages is specific to Microsoft 365 and Reporting Activities to Seismic — each maps to any object or custom field on the other side. | |
| Calendar Events Events synced with scheduling tools and CRMs for meeting visibility. | Library Content Documents, decks, and assets stored in teamsites; created, moved, and retrieved via the Content Management API, each with a contentId. | Calendar Events is specific to Microsoft 365 and Library Content to Seismic — each maps to any object or custom field on the other side. |
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.
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 Seismic through its API, with automatic retries and rate-limit backoff.

Real-time sync, workflow automation, event queues, EDI, and monitoring, for every Microsoft 365–Seismic connection.
Changes in Microsoft 365 or Seismic instantly reflect in both systems. No stale data, no manual imports.
Trigger automated workflows whenever Microsoft 365 or Seismic 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 Seismic record.
Track your Microsoft 365 ⇄ Seismic sync health, view errors, and replay failed events in one click.
Transform legacy EDI complexity into simple database interactions between Microsoft 365 and Seismic.
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 Seismic 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 Seismic 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 Seismic: authenticate both systems, choose the objects to sync (such as Microsoft 365's Users and Teams), map fields visually, and changes propagate both ways in milliseconds — no code required.
Microsoft 365: Access is scoped per permission via Entra ID admin consent, so an integration only sees the workloads it was granted. Seismic: Reporting APIs are ETL-oriented and explicitly not designed for high-frequency, interactive use; they extract batches for a data lake or warehouse. Stacksync's field mapping accounts for these differences between Microsoft 365 and Seismic 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 Microsoft 365 and Seismic records are not retained after a sync operation.
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Microsoft 365 and Seismic connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Microsoft 365–Seismic integration in-house.
Yes — Stacksync ships production-grade connectors for both Microsoft 365 and Seismic. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
Change detection on Microsoft 365: Graph change notifications (webhooks) plus delta queries for incremental sync. On Seismic: Webhooks for content, version, user, group, workflow, DSR, and LiveSend events; the Reporting API v2 is polled for batch historical extracts (ETL-oriented, not high-frequency). Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
