Slack Teams Integration FAQ

Common questions about connecting Slack and Microsoft Teams.

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?

Your client's Microsoft 365 admin needs to approve the connection via a consent link. With Guided Setup, that's all they do - SlackBridge handles bot installation automatically. With Secure Connect, their admin also adds the SlackBridge bot to their Teams workspace manually (simple instructions are provided). Either way, end users just message 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 organization is managed separately with its own linked channels.

How much does Slack Teams integration cost?

SlackBridge is free to start with 1 external organization and 1 linked channel. Our Pro plan at $49.99/month includes 5 external organizations and 50 linked channels. Need more? Pro users can add extra organizations and channels with affordable add-on packs.

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.

What permissions does SlackBridge require?

On the Slack side, SlackBridge requests 12 bot scopes to read, write, and manage channels for bridging. On the Microsoft side, it depends on which setup method you choose. Secure Connect requests 6 read-focused permissions for organizations with strict IT policies. Guided Setup requests 10 permissions to automate bot installation and channel creation. Both require approval from your client's Microsoft 365 tenant administrator. Slack permissions | Secure Connect | Guided Setup
