Two-way sync
Changes in Insightly or Microsoft 365 instantly reflect in both systems. No stale data, no manual imports.
Keep Insightly 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.
The CRM is supposed to be the record of every customer relationship, but customer-relevant information also accumulates in the other tools a team runs. Whatever Microsoft 365 holds or produces that touches a customer, whether conversations, payments, replies, enriched data, or notes, the CRM only benefits if it arrives without someone copying it over.
Stacksync connects OneDrive Files (driveItems), SharePoint Sites & Lists, Teams, Planner & To Do Tasks in Microsoft 365 to Organizations, Leads, Opportunities, Projects in Insightly with bi-directional, real-time sync. Activity and record changes in Microsoft 365 update the matching contact or account in Insightly, and CRM data flows the other way wherever Microsoft 365 can store and use it.
Enriched fields land directly on records in Insightly, and refreshes keep them from going stale.
Charges, refunds, and subscription changes appear on the account in Insightly, so revenue context lives with the relationship.
Owner, lifecycle stage, or account details from Insightly sync into Microsoft 365, so people working there have the context without switching tools.
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.
| Insightly objects | Microsoft 365 objects | |
|---|---|---|
| Tasks Activity records keep follow-ups consistent across systems. | Contacts Personal and org contacts kept consistent with CRM contact records. | |
| Events Calendar items sync for a complete activity timeline. | OneDrive Files (driveItems) File and folder metadata synced for document workflows and audits. | |
| Notes Free-text context attaches to synced records for downstream visibility. | SharePoint Sites & Lists List items read and written like lightweight database tables. | |
| Products Product catalog entries support line-item syncing on opportunities and quotes. | Teams Team and membership data provisioned from upstream systems. | |
| Custom Fields Per-object custom fields carry enrichment and billing data written from external systems. | Planner & To Do Tasks Task items synced with project and work-management tools. | |
| Contacts Person records sync with marketing and support tools to keep one contact list. | Users Entra ID user accounts synced with HR and identity systems. |
