Why teams connect BambooHR and Microsoft 365
Keep the people, teams, and status that Microsoft 365 and BambooHR share aligned in real time, so a hire, role change, or departure recorded in one reaches the other within seconds.
Each tool in Microsoft 365 keeps its own list of who can use it: users, members, or agents, along with the team they sit on and whether they are still active. BambooHR is the authoritative record of the same people as employees, with their department, manager, and employment status. When those two are connected only by manual account admin or a periodic export, the work tools drift: new hires wait days for access, team and manager changes never catch up, and people who have left keep standing accounts.
Stacksync syncs Mail Messages, Calendar Events, Contacts, OneDrive Files (driveItems) in Microsoft 365 with Time Off, Employment Status, Departments and Divisions, Custom Tables in BambooHR bi-directionally and in real time. A person added, moved, or offboarded in BambooHR creates or updates the matching user in Microsoft 365 within seconds, with field-level mapping and conflict resolution in place of spreadsheets and one-off account changes. Where Microsoft 365 captures details of its own, such as a corrected contact or a login identity, those can flow back to BambooHR in whichever direction you configure.
Because the sync is field-level, each system keeps its own extras; only the shared facts, who a person is, which team they belong to, and whether their access should be on, are held in agreement.
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 Feed Compensation and custom-table data to a warehouse for HR analytics with field-level access control.
- 04 Sync Employees and Employment Status to identity and IT systems so new hires are provisioned and departures deactivated automatically.
Common sync patterns
Onboarding: access ready on day one
A new hire recorded in BambooHR creates the matching user in Microsoft 365 with the right team and manager already set, so people can start working without waiting on a provisioning ticket.
Offboarding: no standing access after a departure
When someone is marked as leaving in BambooHR, the matching account in Microsoft 365 is deactivated or flagged, so departures do not leave open access behind.
One employee directory
A person's name, title, contact details, or status corrected in either system updates the other, so both sides stop maintaining separate copies of the same person.
What you can sync between BambooHR 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.
| BambooHR objects | Microsoft 365 objects | How this pairing syncs | |
|---|---|---|---|
| Employees The core person record with personal and work fields; read out to identity, payroll, and IT systems, and written back from recruiting or onboarding tools. | Users Entra ID user accounts synced with HR and identity systems. | Employees is specific to BambooHR and Users to Microsoft 365 — each maps to any object or custom field on the other side. | |
| Job Information Effective-dated job title, department, division, location, and reporting line; synced so org charts and provisioning systems track internal moves. | Groups Microsoft 365 and security groups kept aligned with org structure and access rules. | Job Information is specific to BambooHR and Groups to Microsoft 365 — each maps to any object or custom field on the other side. | |
| Compensation Effective-dated pay rate, schedule, and change reason; read into planning and payroll systems with access restricted to authorized fields. | Mail Messages Exchange Online messages read for logging, archiving, or activity capture. | Compensation is specific to BambooHR and Mail Messages to Microsoft 365 — each maps to any object or custom field on the other side. | |
| Time Off Requests, balances, and policies; read for absence calendars and capacity planning, with approved requests written from an external scheduling tool. | Calendar Events Events synced with scheduling tools and CRMs for meeting visibility. | Time Off is specific to BambooHR and Calendar Events to Microsoft 365 — each maps to any object or custom field on the other side. | |
| Employment Status Effective-dated hire, leave, and termination status; drives automated provisioning and deprovisioning in downstream identity and license systems. | Contacts Personal and org contacts kept consistent with CRM contact records. | Employment Status is specific to BambooHR and Contacts to Microsoft 365 — each maps to any object or custom field on the other side. | |
| Departments and Divisions Org-structure list values; synced to keep cost centers and team groupings consistent across ERP, identity, and analytics systems. | OneDrive Files (driveItems) File and folder metadata synced for document workflows and audits. | Departments and Divisions is specific to BambooHR and OneDrive Files (driveItems) to Microsoft 365 — each maps to any object or custom field on the other side. |
How changes propagate between BambooHR 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.
BambooHR Microsoft 365 Sub-second propagation
DetectionBambooHR notifies Stacksync of record changes through webhook events. The Get Updated Employee IDs endpoint (last-changed timestamps) returns employees inserted, updated, or deleted since a cursor for efficient polling.
DeliveryEach detected change is written to Microsoft 365 through its API, with automatic retries and rate-limit backoff.
Microsoft 365 BambooHR 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 BambooHR through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- BambooHR: Requests are rate-limited per API key with standard REST throttling (429 on excess); bulk reads are best done through saved Reports or the updated-IDs delta endpoint rather than per-employee calls.

-
Change detection on BambooHR: The Get Updated Employee IDs endpoint (last-changed timestamps) returns employees inserted, updated, or deleted since a cursor for efficient polling; webhooks can fire on monitored field 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.
