Why teams connect Microsoft 365 and Zendesk
Stop re-entering the same information in Microsoft 365 and Zendesk: 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 SharePoint Sites & Lists, Teams, Planner & To Do Tasks, Users in Microsoft 365 with Attachments, Ticket Forms, Tickets, Tickets Comments in Zendesk 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
- Keep CRM contacts and Microsoft 365 contacts aligned in both directions.
- Sync employee records from an HR system into Entra ID users and group memberships.
- Consolidate several Zendesk instances into one reporting database after a merger or brand split.
- Sync tickets, users, and organizations into Postgres so support analytics run on SQL instead of repeated API pulls.
Where Zendesk is where the team documents or plans: keep its data fed
Information that originates in Microsoft 365 stays current in Zendesk 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.
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.
