Why teams connect Microsoft 365 and Vtiger CRM

Sync what happens in Microsoft 365 with the customer records in Vtiger CRM, in real time and in both directions.

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 Contacts, Organizations, Leads, Opportunities in Vtiger CRM with bi-directional, real-time sync. Activity and record changes in Microsoft 365 update the matching contact or account in Vtiger CRM, and CRM data flows the other way wherever Microsoft 365 can store and use it.

Common use cases

  • Mirror calendar events into scheduling or CRM tools so meetings appear on customer timelines.
  • Sync SharePoint lists with operational databases so business users edit in SharePoint while systems read SQL.
  • Two-way contact and organization sync between Vtiger and a billing or ERP system.
  • Sync Cases to an external help desk or engineering tracker so support and product teams work from the same tickets.

Owner, lifecycle stage, or account details from Vtiger CRM sync into Microsoft 365, so people working there have the context without switching tools.

Enriched fields land directly on records in Vtiger CRM, and refreshes keep them from going stale.
