Why teams connect BetterContact and Microsoft 365
Flow BetterContact data into Microsoft 365 in real time — no exports, no schedulers, no custom scripts.
BetterContact is a read-only source: Stacksync reads its data in real time and delivers it into Microsoft 365, so Microsoft 365 always reflects the current state of BetterContact — without exports, scripts, or schedulers.
Two tools in the daily stack often hold overlapping information: the same people, the same companies, or the same pieces of work, described twice. The tools do different jobs, so consolidating is not the answer; the overlap just needs to stop drifting.
Stacksync syncs Company, Lead Finder Search, Enrichment Request, Enriched Contact in BetterContact with Teams, Planner & To Do Tasks, Users, Groups in Microsoft 365 in real time. You choose which records overlap, map the fields that should match, and pick a direction or let changes flow both ways. From then on, an update made in either tool is reflected in the other within seconds, without exports or copy-paste.
Because the sync is field-level, each tool keeps its own extras; only the shared data is held in agreement.
Common use cases
- 01 Backfill a warehouse of contacts with waterfall enrichment across 20+ data providers.
- 02 Feed outbound sequencing tools with verified contact data before campaigns launch.
- 03 Archive mail and file metadata into a warehouse for compliance and activity analytics.
- 04 Keep CRM contacts and Microsoft 365 contacts aligned in both directions.
Common sync patterns
Handoffs between teams
When work started in one tool continues in the other, the shared fields travel with it automatically.
Where both tools track people or companies: one consistent record
Contact and company details corrected in either tool update the other, so nobody works from the old version.
Where one tool produces events: mirror them in the other
Payments, replies, messages, or tickets created in one tool can create or update matching records in the other, keeping context in one place.
What you can sync between BetterContact 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.
| BetterContact objects | Microsoft 365 objects | How this pairing syncs | |
|---|---|---|---|
| Lead Finder Search Prospect discovery by people and company filters, returning enriched lead profiles. | Planner & To Do Tasks Task items synced with project and work-management tools. | Lead Finder Search is specific to BetterContact and Planner & To Do Tasks to Microsoft 365 — each maps to any object or custom field on the other side. | |
| Enrichment Request Batch or single submissions of up to 100 contacts per request for waterfall enrichment. | Users Entra ID user accounts synced with HR and identity systems. | Enrichment Request is specific to BetterContact and Users to Microsoft 365 — each maps to any object or custom field on the other side. | |
| Enriched Contact Verified work emails and mobile numbers with job title, LinkedIn profile, location, and skills. | Groups Microsoft 365 and security groups kept aligned with org structure and access rules. | Enriched Contact is specific to BetterContact and Groups to Microsoft 365 — each maps to any object or custom field on the other side. | |

How changes propagate between BetterContact 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.
BetterContact Microsoft 365 Sub-second propagation
DetectionBetterContact notifies Stacksync of record changes through webhook events. Job-based delivery — enrichment results arrive by webhook push or polling of the results endpoint.
DeliveryEach detected change is written to Microsoft 365 through its API, with automatic retries and rate-limit backoff.
Microsoft 365 BetterContact Sub-second propagation
DetectionMicrosoft 365 notifies Stacksync of record changes through webhook events. Graph change notifications (webhooks) plus delta queries for incremental sync.
DeliveryBetterContact does not accept inbound record writes, so this direction carries requests rather than records: BetterContact's output flows back as field updates on the originating Microsoft 365 records.
Rate-limit considerations
- BetterContact: Batches capped at 100 contacts per enrichment request.
