## Domains Table

### Table Columns

The domains table displays all registered domains with the following information:

| Column        | Description                                                 |
| ------------- | ----------------------------------------------------------- |
| **Domain**    | Domain name with indicators for default and initial domains |
| **Company**   | Associated company (visible in global view)                 |
| **Default**   | Whether this is the default domain for the tenant           |
| **Verified**  | Domain verification status                                  |
| **Services**  | Microsoft 365 services enabled for the domain               |

### Domain Indicators

Domains may display special indicators:

| Indicator         | Meaning                                       |
| ----------------- | --------------------------------------------- |
| **Star icon**     | This is the default domain for the tenant     |
| **Initial badge** | This is the initial `.onmicrosoft.com` domain |

### Verification Status

| Status         | Description                                         |
| -------------- | --------------------------------------------------- |
| **Verified**   | Domain ownership has been confirmed via DNS records |
| **Unverified** | Domain is registered but not yet verified           |

<Note>
  Unverified domains cannot be used for email or other Microsoft 365 services until verification is complete.
</Note>

### Authentication Types

| Type          | Description                                                          |
| ------------- | -------------------------------------------------------------------- |
| **Managed**   | Authentication handled directly by Microsoft 365                     |
| **Federated** | Authentication handled by an external identity provider (e.g., ADFS) |

### Services

The Services column shows which Microsoft 365 services are enabled for each domain:

* **Email** - Exchange Online email routing
* **OfficeCommunicationsOnline** - Microsoft Teams and Skype
* **Intune** - Device management
* **SharePoint** - SharePoint Online sites

If a domain has more than three services, a badge shows the count of additional services.

* **Sort** - Click any column header to sort the table
* **Search** - Use the search box to find specific domains
* **Company Filter** - Multi-select dropdown to filter by one or more companies
* **Default Filter** - Filter to show only default or non-default domains
* **Verified Filter** - Filter by verification status
* **Auth Type Filter** - Filter by authentication type

### Exporting Data

Users with the **manage\_m365** permission can export domain data:

1. Click the **Export** button in the table toolbar
2. Choose your export format
3. The export includes domain name, company, verification status, authentication type, and services

## Company Context

The domains view adapts based on your current context:

| View             | Behavior                                                 |
| ---------------- | -------------------------------------------------------- |
| **Global View**  | Shows domains from all companies, Company column visible |
| **Company View** | Shows domains for the selected company only              |

Switch between views using the company selector in the main navigation.

## Prerequisites

Before using M365 Domains:

1. **Microsoft 365 Integration** - Enable in Settings > Integrations for each company
2. **Azure AD Permissions** - The integration requires appropriate Graph API permissions
3. **User Permissions** - Requires access to the M365 module

## Troubleshooting

### Domains Not Showing

<AccordionGroup>
  <Accordion title="No domains appear in the table">
    **Possible causes:**

    * M365 integration not configured for any companies
    * Integration credentials expired or invalid
    * Initial sync has not completed

    **Solution:**

    1. Verify M365 integration is active in Settings > Integrations
    2. Wait for the automatic sync to complete
    3. Check integration permissions in Azure AD
  </Accordion>

  <Accordion title="Domain shows as unverified">
    **Possible causes:**

    * DNS verification records not configured
    * DNS propagation not complete
    * Verification record removed

    **Solution:**

    1. Check DNS records in your domain registrar
    2. Verify TXT or MX records match Microsoft requirements
    3. Allow up to 72 hours for DNS propagation
  </Accordion>

  <Accordion title="Services column shows unexpected values">
    **Possible causes:**

    * Domain not configured for all services
    * Service configuration changed in Microsoft 365

    **Solution:**

    1. Review domain configuration in Microsoft 365 admin center
    2. Wait for automatic sync to update the data
  </Accordion>
</AccordionGroup>

## Best Practices

### Domain Management

1. **Verify Custom Domains** - Ensure all custom domains are verified to enable full functionality
2. **Review Default Domain** - Confirm the correct domain is set as default for each tenant
3. **Monitor Authentication** - Track federated vs. managed authentication for security auditing

### Regular Monitoring

* **Monthly** - Review domain verification status across all companies
* **Quarterly** - Audit domain authentication types and service configurations
* **As Needed** - Check domains when adding new companies or tenants
