# \[Progic\] How to Enable Custom Streaming (RTMP-Out) in Microsoft Teams for Live-streaming?
## Understanding Meeting Policies, App Permissions, and Access Governance
This article guides administrators on configuring *Custom Streaming in Microsoft Teams*, a feature used to broadcast meetings and webinars to external platforms compatible with RTMP-Out.
For this feature to work correctly, you must validate two main areas: the **meeting policy**, which enables live streaming, and the **app policy**, which allows authorized users to use the Custom Streaming application.
- [**Custom Streaming Application**](https://help.progic.com.br/en/how-to-enable-custom-streaming-microsoft-teams-livestreaming#custom-streaming)
- [**Prerequisites**](https://help.progic.com.br/en/how-to-enable-custom-streaming-microsoft-teams-livestreaming#prerequisites)
- [**Step 1 – Verify Application Availability**](https://help.progic.com.br/en/how-to-enable-custom-streaming-microsoft-teams-livestreaming#step1)
- [**Step 2 – Enable the Application at the Organizational Level**](https://help.progic.com.br/en/how-to-enable-custom-streaming-microsoft-teams-livestreaming#step2)
- **[Step 3 – Restrict Access to Authorized Users Only](https://help.progic.com.br/en/how-to-enable-custom-streaming-microsoft-teams-livestreaming#step3)**
- [**Step 4 – Verify Meeting Policy Requirements**](https://help.progic.com.br/en/how-to-enable-custom-streaming-microsoft-teams-livestreaming#step4)

### The Custom Streaming App
The *Custom Streaming* app allows Microsoft Teams meeting and webinar organizers to stream content to external platforms compatible with RTMP, including enterprise streaming solutions, private video platforms, and content delivery services.
*For large enterprise environments, it is recommended to:*
- Enable the app in the Teams organizational catalog.
- Keep the app unavailable to most users.
- Grant access only to specific users or groups.
- Control functionality through Microsoft Teams app policies and meeting policies.
This approach reduces risks of misuse, unauthorized broadcasts, and accidental exposure of corporate information.
### Prerequisites
The administrator must hold one of the following roles:
- Teams Administrator
- Global Administrator
Additionally:
- The app must be allowed in the Microsoft Teams Admin Center.
- Authorized users must have licensing compatible with the meeting and webinar features used by the organization.
- Meeting policies must allow RTMP streaming where applicable.
### Step 1 – Verify App Availability
Access the Microsoft Teams Admin Center:
- Go to **Teams Apps → Manage Apps**.
- Search for: *Custom Streaming*.
- Validate that the app:
- Is published by Microsoft.
- Has the status **Allowed**.
- Is not explicitly blocked.
If it is blocked:
- Open the app.
- Select **Allow**.
- Save the changes.
*Important: Allowing the app at this stage only makes it available for use in the organization. It does not grant access to end-users.*
### Step 2 – Enable the App at the Organizational Level
After locating the app:
- Go to **Teams Apps → Manage Apps → Custom Streaming**.
- Confirm that the status is **Allowed**.
*This procedure enables the app for organizational governance, allowing it to be subsequently granted to specific users.*
### Step 3 – Granular Access Control per User (Recommended)
### Organizations using App-Centric Management
Microsoft is progressively migrating tenants to the **App-Centric Management** model. In this model, control is managed directly within the app settings.
- Access: **Teams Apps → Manage Apps**.
- Open the app: **Custom Streaming**.
- Select: **Users and Groups**.
- Click: **Edit Availability**.
| **Option** | **Description** |
| --- | --- |
| **Everyone** | All users in the organization will be able to use the app. |
| **Specific Users or Groups** | Only defined users or groups will have access. |
| **No one** | The app will be blocked for the entire organization. |
### Recommended Configuration
- Select: **Specific Users or Groups**.
- Add: Individual authorized users, Microsoft Entra ID Security Groups, Microsoft 365 Groups, or dynamic corporate groups.
- Click **Apply** and wait for policy propagation.
### Step 4 – Organizations Still Using App Permission Policies
For tenants not yet migrated to the App-Centric Management model:
1. **Create Permission Policy:** Access **Teams Apps → Permission Policies**, select **Add**, and name it (e.g., *CustomStreaming-AllowedUsers*). Set "Custom Apps" to "Allow specific apps" and add *Custom Streaming*.
2. **Assign Policy:** Access **Users → Manage Users**, select the authorized user, go to **Policies**, and assign the newly created policy.
### Step 5 – Using Groups Instead of Individual Users
For large organizations, it is strongly recommended to use security groups to improve **Governance**, **Scalability**, and **Auditing**.
### Step 6 – Enable Streaming in Meeting Policies
Even with the app available, you must ensure meeting policies allow it:
- Go to **Meetings → Meeting Policies**.
- Ensure the policy assigned to authorized users allows:
- Streaming to external platforms.
- RTMP Out.
- Streaming features compatible with the strategy adopted by the organization.
- If the functionality is disabled in the Meeting Policies, the user will be able to see the app, but will not be able to start the stream.
### **Recommended Process for Corporate Environments**
- Allow the app in the organizational catalog.
- Configure availability as: **Specific Users and Groups**.
- Create a dedicated group: *SG-M365-Teams-CustomStreaming*.
- Associate the app exclusively with that group.
- Assign appropriate meeting policies to the users in that group.
- Perform periodic access reviews.
### **Security Considerations**
Before enabling the use of Custom Streaming, it is recommended to evaluate:
- Classification of meetings eligible for streaming;
- Need for prior approval for external events;
- Retention and recording policies;
- Protection of confidential information;
- Local and international compliance requirements;
- Integration with external streaming platforms.
It is also recommended to maintain a formal record of users authorized to use external streaming on behalf of the organization.
### **Expected Result**
After the recommended configuration:
| **Item** | **Result** |
| --- | --- |
| App available in the tenant | Yes |
| Standard users can use it | No |
| Authorized users can use it | Yes |
| Centralized IT control | Yes |
| Corporate governance maintained | Yes |
| Scalability for multinational environments | Yes |
---
*Note: In tenants already migrated to the App-Centric Management model, Microsoft recommends controlling availability directly by the app, assigning specific users and groups to the app, replacing old App Permission Policies.*
