Why teams connect Microsoft 365 and SendGrid
Stop re-entering the same information in Microsoft 365 and SendGrid: 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 Teams, Planner & To Do Tasks, Users, Groups in Microsoft 365 with Email Activity, Contacts, List, Segments in SendGrid 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
- Sync employee records from an HR system into Entra ID users and group memberships.
- Mirror calendar events into scheduling or CRM tools so meetings appear on customer timelines.
- Stream Event Webhook engagement data into a Postgres database or warehouse for campaign and deliverability reporting
- Keep product-usage attributes from an operational database updated on SendGrid contacts to drive lifecycle segments
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.
Where SendGrid is where the team documents or plans: keep its data fed
Information that originates in Microsoft 365 stays current in SendGrid instead of going stale after a one-time paste.
What you can sync between Microsoft 365 and SendGrid
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 | SendGrid objects | |
|---|---|---|
| Planner & To Do Tasks Task items synced with project and work-management tools. | List Synced with incremental and full sync per the Stacksync docs. | |
| Users Entra ID user accounts synced with HR and identity systems. | Segments Query-based contact groups whose membership SendGrid computes from contact fields. | |
| Groups Microsoft 365 and security groups kept aligned with org structure and access rules. | Categories Synced with incremental and full sync per the Stacksync docs. | |
| Mail Messages Exchange Online messages read for logging, archiving, or activity capture. | Senders Synced with incremental and full sync per the Stacksync docs. | |
| Calendar Events Events synced with scheduling tools and CRMs for meeting visibility. | Single Sends One-off marketing campaigns whose stats are read back for reporting. | |
| Contacts Personal and org contacts kept consistent with CRM contact records. | Unsubscribe Groups Synced with incremental and full sync per the Stacksync docs. |

How the Microsoft 365 and SendGrid connectors work
Microsoft 365
- Integration surface
- REST API (Microsoft Graph)
- Authentication
- OAuth 2.0 via Microsoft Entra ID, with delegated or application permissions
- Change detection
- Graph change notifications (webhooks) plus delta queries for incremental sync
- Capabilities
- read · write · webhooks
SendGrid
- Integration surface
- REST API (v3)
- Authentication
- API key (create in SendGrid Settings > API Keys with Custom Access / Full Access for the objects to sync; key begins with "SG")
- Change detection
- Event Webhook posts delivery and engagement events (processed, delivered, open, click, bounce, spam report) to an HTTP endpoint; contact and list changes are detected by polling
- Capabilities
- read · write · webhooks
- Rate limits
- Subject to the platform's API rate limits; contact upserts are batched, asynchronous jobs rather than per-row writes

FAQ
Microsoft 365 and SendGrid integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Microsoft 365 and SendGrid: authenticate both systems, choose the objects to sync (such as Microsoft 365's Planner & To Do Tasks and Users), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Microsoft 365: Delta queries return only resources changed since the last sync token, which keeps incremental syncs cheap on large tenants. SendGrid: Email Activity access requires an add-on subscription in SendGrid; without it the Email Activity API is not available. Stacksync's field mapping accounts for these differences between Microsoft 365 and SendGrid 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 SendGrid 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 SendGrid connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Microsoft 365–SendGrid integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Microsoft 365 and SendGrid. 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 SendGrid: Event Webhook posts delivery and engagement events (processed, delivered, open, click, bounce, spam report) to an HTTP endpoint; contact and list changes are detected by polling. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
