Two-way sync
Changes in Active Directory or Microsoft 365 instantly reflect in both systems. No stale data, no manual imports.
Keep Active Directory and Microsoft 365 in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
Active Directory is where a company records who its people are: their accounts, the groups and roles they hold, and the attributes attached to each one. Microsoft 365 is where a slice of those same people do their work, as agents, members, or seats, and every one of them needs a matching account with the right access. When a directory and a productivity tool are maintained by hand, someone added, moved, or offboarded in one becomes a stale entry in the other within the hour.
Stacksync syncs Contacts, OneDrive Files (driveItems), SharePoint Sites & Lists, Teams in Microsoft 365 with Group memberships, Devices, Directory roles, Service principals & applications in Active Directory bi-directionally and in real time. A user created, renamed, moved between groups, or deactivated in either system updates the matching record in the other within seconds, with field-level mapping and conflict resolution in place of CSV uploads and nightly IT batch jobs.
That matters most at the edges of employment. When both systems agree on who has an account, which groups they belong to, and whether they are still active, granting access on day one and revoking it on the last day stops being a manual checklist that trails the directory.
Moving a user between groups or roles in Active Directory updates their team, permission set, or seat in Microsoft 365, so what someone can do reflects where they sit in the directory.
People matched across both systems on email or an external ID stay linked, so every account and action in Microsoft 365 ties back to the right identity in Active Directory.
A user added to Active Directory, or moved into a group inside it, gets the matching account or membership created in Microsoft 365, so a new hire can start working without a separate setup ticket.
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.
| Active Directory objects | Microsoft 365 objects | How this pairing syncs | |
|---|---|---|---|
| Users User accounts in Entra ID and on-prem AD DS; synced two-way to create, update attributes, and enable or disable accounts. | Users Entra ID user accounts synced with HR and identity systems. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Groups Security and Microsoft 365 groups; synced two-way including name, type, and owner, with membership tracked separately. | Groups Microsoft 365 and security groups kept aligned with org structure and access rules. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Organizational units On-prem AD DS containers (LDAP organizationalUnit) used to scope which users and groups a sync includes. | Mail Messages Exchange Online messages read for logging, archiving, or activity capture. | Organizational units is specific to Active Directory and Mail Messages to Microsoft 365 — each maps to any object or custom field on the other side. | |
| Organizational contacts Directory contact objects (orgContact); synced for shared address-book and CRM person records. | Calendar Events Events synced with scheduling tools and CRMs for meeting visibility. | Organizational contacts is specific to Active Directory and Calendar Events to Microsoft 365 — each maps to any object or custom field on the other side. | |
| Group memberships Member and owner links between users and groups; membership add/remove changes are surfaced by delta query. | Contacts Personal and org contacts kept consistent with CRM contact records. | Group memberships is specific to Active Directory and Contacts to Microsoft 365 — each maps to any object or custom field on the other side. | |
| Devices Registered and joined device objects; typically read into a database for inventory and compliance reporting. | OneDrive Files (driveItems) File and folder metadata synced for document workflows and audits. | Devices is specific to Active Directory and OneDrive Files (driveItems) to Microsoft 365 — 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.
DetectionActive Directory notifies Stacksync of record changes through webhook events. Microsoft Graph delta query (change tracking) for Users and Groups, plus change-notification subscriptions (webhooks) for near-real-time triggers.
DeliveryEach detected change is written to Microsoft 365 through its API, with automatic retries and rate-limit backoff.
DetectionMicrosoft 365 notifies Stacksync of record changes through webhook events. Graph change notifications (webhooks) plus delta queries for incremental sync.

Real-time sync, workflow automation, event queues, EDI, and monitoring, for every Active Directory–Microsoft 365 connection.
Changes in Active Directory or Microsoft 365 instantly reflect in both systems. No stale data, no manual imports.
Trigger automated workflows whenever Active Directory or Microsoft 365 data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.
Handle millions of events per minute without losing a single Active Directory or Microsoft 365 record.
Track your Active Directory ⇄ Microsoft 365 sync health, view errors, and replay failed events in one click.
Transform legacy EDI complexity into simple database interactions between Active Directory and Microsoft 365.
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 Active Directory and Microsoft 365 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 Active Directory and Microsoft 365 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 Active Directory and Microsoft 365: authenticate both systems, choose the objects to sync (such as Active Directory's Users and Groups), 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 Active Directory 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 Active Directory and Microsoft 365 connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Active Directory–Microsoft 365 integration in-house.
Yes — Stacksync ships production-grade connectors for both Active Directory and Microsoft 365. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
Change detection on Active Directory: Microsoft Graph delta query (change tracking) for Users and Groups, plus change-notification subscriptions (webhooks) for near-real-time triggers; on-prem AD DS uses the DirSync control and uSNChanged polling. 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: Contacts, OneDrive Files (driveItems), SharePoint Sites & Lists, Teams, plus custom fields where Microsoft 365 exposes them. On the Active Directory side: Group memberships, Devices, Directory roles, Service principals & applications. Stacksync auto-detects both schemas and converts types between the two systems.
