+## What Can the Invitation Link Do for You?
+
+The auto-generated invitation link is a powerful tool that helps instructors efficiently manage learner access and streamline the enrollment process.
+
+### 1. Precise Team Access Control
+
+Your invitation link provides targeted access management:
+
+- **Specific Team Access**: Only members of your selected teams can access the content through this link
+- **Automatic Role Assignment**: Users who accept the invitation automatically receive the "Academy Learner" role
+- **Organization Boundary Protection**: Only users within your [organization](https://docs.layer5.io/cloud/identity/organizations/) can use this invitation
+
+### 2. Flexible Sharing and Distribution
+
+**Automated Email Distribution:**
+- The system automatically sends invitation emails to specified team members
+- Emails include course descriptions and one-click access links
+- Reduces your manual notification workload and ensures consistent messaging
+
+**Direct Sharing Options:**
+- Copy and send the invitation link directly to team members
+- Share through collaboration tools like Slack, Microsoft Teams, or Discord
+- Embed the link in internal documentation, wikis, or learning portals
+
+

+{{< /alert >}}
+
+**Customizable Properties:**
+
+### 1. Emails - Invitation Email List
+
+Configure who receives the invitation:
+
+- **Supported Formats:**
+  - Individual emails: `test@domain.com`
+  - Domain-wide invitations: `@domain.com` (invites all users from that domain)
+- **Duplicate Handling**: The system automatically merges duplicate entries
+- **Quantity Recommendations:**
+  - Small team invitations: 10-50 email addresses
+  - Department-level invitations: 100-200 email addresses
+  - Large organizations: Use domain wildcards like `@company.com` instead of listing individual emails
+
+### 2. Expires At - Expiration Settings
+
+Control when the invitation expires:
+

+- **What happens at expiration?**

+  - If the expiration time has passed, users cannot proceed with the invitation

+
+### 3. Quota - Usage Limits
+
+Set limits on how many users can accept the invitation:
+
+- **When quota is exceeded:**

+  - Users beyond the quota cannot join, even with a valid invitation link
+- **Recovery options:**
+  - If quota is reached, you can increase the quota to restore access
+  - Admin console provides real-time usage monitoring
+
+### 4. Teams - Team Assignment List
+
+Specify which teams invited users will join:
+
+- **Team Selection**: Choose from available teams via dropdown menu
+- **Multiple Teams**: You can assign users to multiple teams
+- **No Teams Available**: If your organization has no teams, [create them](https://docs.layer5.io/cloud/identity/teams/) first. Users will be added to all successfully configured teams
+
+{{< alert type="info" title="Team Structure Changes" >}}

+- Some teams may be merged or deleted
+- New users can still join remaining valid teams
