Why teams connect GitHub and Microsoft 365

Stop re-entering the same information in GitHub and Microsoft 365: Stacksync keeps the records they share consistent in real time, in both directions.

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 Releases, Workflow runs (Actions), Organizations and Teams, Users in GitHub with Mail Messages, Calendar Events, Contacts, OneDrive Files (driveItems) 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 Create GitHub issues automatically from records written elsewhere, such as bug reports logged in a CRM case object.
  • 02 Publish release data into customer-communication tools when a new version ships.
  • 03 Mirror calendar events into scheduling or CRM tools so meetings appear on customer timelines.
  • 04 Sync SharePoint lists with operational databases so business users edit in SharePoint while systems read SQL.

Common sync patterns

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.

Where Microsoft 365 is where the team documents or plans: keep its data fed

Information that originates in GitHub stays current in Microsoft 365 instead of going stale after a one-time paste.

Handoffs between teams

When work started in one tool continues in the other, the shared fields travel with it automatically.

What you can sync between GitHub 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.

GitHub objects Microsoft 365 objects How this pairing syncs
Users Author and assignee identities matched to internal directories. 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.
Pull Requests Review state, status checks, and merge status feed engineering dashboards and workflow tools. SharePoint Sites & Lists List items read and written like lightweight database tables. Pull Requests is specific to GitHub and SharePoint Sites & Lists to Microsoft 365 — each maps to any object or custom field on the other side.
Commits Read-only history used to link code activity to tickets and releases. Teams Team and membership data provisioned from upstream systems. Commits is specific to GitHub and Teams to Microsoft 365 — each maps to any object or custom field on the other side.
Releases Tagged versions synced into changelogs, CRMs, or customer-notification systems. Planner & To Do Tasks Task items synced with project and work-management tools. Releases is specific to GitHub and Planner & To Do Tasks to Microsoft 365 — each maps to any object or custom field on the other side.
Workflow runs (Actions) CI results synced into incident and reporting systems. Groups Microsoft 365 and security groups kept aligned with org structure and access rules. Workflow runs (Actions) is specific to GitHub and Groups to Microsoft 365 — each maps to any object or custom field on the other side.
Organizations and Teams Membership data synced with identity systems and HR directories for access reviews. Mail Messages Exchange Online messages read for logging, archiving, or activity capture. Organizations and Teams is specific to GitHub and Mail Messages to Microsoft 365 — each maps to any object or custom field on the other side.

How changes propagate between GitHub 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.

GitHub Microsoft 365 Sub-second propagation

DetectionGitHub notifies Stacksync of record changes through webhook events. Webhooks with a broad event catalog covering issues, pull requests, pushes, and releases.

DeliveryEach detected change is written to Microsoft 365 through its API, with automatic retries and rate-limit backoff.

Microsoft 365 GitHub Sub-second propagation

DetectionMicrosoft 365 notifies Stacksync of record changes through webhook events. Graph change notifications (webhooks) plus delta queries for incremental sync.

Rate-limit considerations

  • GitHub: Authenticated REST requests are limited to 5,000 per hour per user; GitHub Apps scale limits per installation.
