Connect Slack with Microsoft Teams
The ultimate interoperability layer. Bi-directional sync for messages, files, reactions, and threads. Unite your organization.
Unite Your Text-Stack
Bridge the gap between the two most powerful collaboration platforms in the world.
The "Two HQ" Dilemma
DevOps lives in Slack. Sales and Management live in Teams. Urgent issues fall through the cracks because the two HQs are effectively invisible to each other.
SyncRivo creates a unified nervous system. Alerts in Slack reach Management in Teams instantly. Collaboration happens in real-time.
Shadow IT & Guest Accounts
Employees create guest accounts in each other's tenants to communicate, leading to data sprawl, security risks, and admin nightmares.
Stop the guest account madness. Users stay in their home tenant. SyncRivo handles the secure federation invisible to the end user.
Workflow Breaks
Jira notifications go to Slack, but the decision maker is in Teams. Workflows stall waiting for copy-paste updates.
Mirror your notification channels. Ensure visibility across the entire organization, regardless of the tool they prefer.

Proven Connection Scenarios
How market leaders solve the duality of Slack and Teams
DevOps & Management Bridge
Your SREs use Slack for incident response. Your Executives use Teams for comms. Bridge the #incident channel so leaders stay informed without leaving Teams.
Acquisition Integration
Bought a cool startup that loves Slack? Don't kill their culture by forcing Teams on Day 1. Connect the platforms and migrate slowly (or never).
Shared Service Centers
A central IT or HR service desk in Teams can support internal customers who prefer Slack. One queue, multiple entry points.
Community Collaboration
Host a community in a public Slack workspace while your internal team manages moderation and replies from their internal Teams tenant.
Common Questions
Yes. SyncRivo supports mapping private Slack channels to private Teams channels (or standard channels), respecting user membership and permissions on both sides.
Threads are fully supported. A reply in a Slack thread appears as a reply in the Teams conversation, maintaining full context. Thread hierarchy is preserved bidirectionally.
Yes. SyncRivo is built to a SOC 2-aligned architecture with OAuth2 per-integration, per-tenant data isolation, RBAC controls, and full audit logs. It is designed to pass enterprise InfoSec reviews and supports HIPAA-eligible workloads.
No. SyncRivo sits between the two platforms via their native APIs — Slack Events API and Microsoft Graph API — so employees on either platform communicate normally without needing guest accounts, external federation, or any special permissions beyond what SyncRivo is granted during setup.
SyncRivo works with Slack Pro, Business+, and Enterprise Grid plans. For bidirectional channel sync at scale, Enterprise Grid is recommended as it provides the full Slack Events API surface SyncRivo uses for real-time delivery.
SyncRivo processes messages in under 100ms from the moment a Slack event or Teams webhook fires. Users on both platforms see messages in near real-time — typically within 1 second end-to-end.
Yes — this is one of the most common enterprise use cases. SyncRivo bridges the two organizations during the coexistence period of a merger or acquisition, allowing both teams to keep working in their preferred tool while communicating seamlessly. You can run the bridge as long as needed, then decommission it once migration is complete.
