Can Slack and Teams integrate?

Yes! While there's no native integration between Slack and Microsoft Teams, SlackBridge provides a seamless bridge. Messages you send in Slack appear in your client's Teams channel, and their replies come back to Slack instantly.

How secure is SlackBridge?

SlackBridge uses OAuth 2.0 for authentication and the official Microsoft Graph API for Teams integration. We're 100% serverless — messages relay in real-time and full message content is not stored. Temporary metadata is retained for up to 7 days to support thread synchronization. All connections are encrypted on enterprise-grade infrastructure.

Do my clients need to install anything?

No. Your client contact receives an invite link and can approve the connection themselves or forward it to their IT administrator. Once approved, their users message you normally in Teams - they don't know you're on Slack.

What's the difference between SlackBridge and migrating from Slack to Teams?

Migration means abandoning Slack entirely and moving to Teams. SlackBridge lets you keep using Slack while communicating with Teams users. No migration, no retraining, no lost integrations.

Can I connect to multiple Teams tenants?

Yes! Agencies and consultancies can connect their single Slack workspace to multiple client Teams tenants. Each client connection is managed separately with its own channel mappings.

How much does Slack Teams integration cost?

SlackBridge offers a free tier for small teams getting started. For larger teams and enterprises, pricing is based on the number of active connections and message volume. Visit our pricing page for details.

Is this the same as Slack Connect?

No. Slack Connect requires both parties to use Slack. SlackBridge works when your client uses Microsoft Teams and doesn't want another app. They stay in Teams, you stay in Slack.
