Are you having trouble sending emails from your Azure Web App using Azure Communication Email? You’re not alone! In this article, we’ll take a deep dive into the common issues and provide you with step-by-step solutions to get your email sending up and running smoothly.

Common Issues with Azure Web App and Azure Communication Email

Before we dive into the troubleshooting, let’s take a look at some common issues that might be causing the problem:

• Authentication and Authorization issues with Azure Communication Email
• Incorrect configuration of Azure Web App and Azure Communication Email
• Dependency issues with NuGet packages
• Versions compatibility issues with Azure Web App and Azure Communication Email
• Firewall and Network restrictions

Step 1: Verify Azure Communication Email Configuration

Let’s start by verifying that your Azure Communication Email configuration is correct. Follow these steps:

1. Log in to the Azure portal and navigate to the Azure Communication Email resource.
2. Click on the “Configuration” tab and verify that the ” Sender Domain” and “Sender Address” are correctly configured.
3. Make sure the “Email service” is set to “Azure Communication Email” and the “Authentication” is set to “Enabled”.
4. Take note of the “Username” and “Password” for later use.

  
    {
      "SenderDomain": "yourdomain.com",
      "SenderAddress": "your-email-address@yourdomain.com",
      "EmailService": "AzureCommunicationEmail",
      "Authentication": "Enabled",
      "Username": "your-username",
      "Password": "your-password"
    }
  

Step 2: Verify Azure Web App Configuration

Now, let’s move on to verifying the Azure Web App configuration:

1. Log in to the Azure portal and navigate to the Azure Web App resource.
2. Click on the “Configuration” tab and scroll down to the “App settings” section.
3. Verify that the “AzureCommunicationEmail__Username” and “AzureCommunicationEmail__Password” are correctly configured with the values from Step 1.
4. Make sure the “Email__SenderAddress” is set to the correct sender address.

  
    {
      "AzureCommunicationEmail__Username": "your-username",
      "AzureCommunicationEmail__Password": "your-password",
      "Email__SenderAddress": "your-email-address@yourdomain.com"
    }
  

Step 3: Install and Configure NuGet Packages

Next, let’s ensure that the correct NuGet packages are installed and configured:

1. Open your Azure Web App project in Visual Studio.
2. Right-click on the project and select “Manage NuGet Packages”.
3. Search for and install the “Azure.Communication.Email” package.
4. Verify that the package is installed correctly and the version is compatible with your Azure Web App.

  
    Install-Package Azure.Communication.Email
  

Step 4: Update Azure Web App Code

Now, let’s update the Azure Web App code to use the correct email configuration:

In your Azure Web App code, update the email sending logic to use the Azure Communication Email NuGet package:

  
    using Azure.Communication.Email;

    // Create a new instance of the EmailClient
    EmailClient emailClient = new EmailClient(new Uri("https://your-communication-email-endpoint.communication.azure.com"));

    // Create a new email message
    EmailMessage emailMessage = new EmailMessage(
        sender: "your-email-address@yourdomain.com",
        content: new EmailContent("Subject", "Body"));

    // Add recipients to the email message
    emailMessage.Recipients.Add(new EmailRecipient("recipient-email-address@example.com"));

    // Send the email message
    emailClient.SendAsync(emailMessage).GetAwaiter().GetResult();
  

Step 5: Check Firewall and Network Restrictions

Finally, let’s check for any firewall and network restrictions that might be blocking the email sending:

Verify that the Azure Web App has the necessary outbound connectivity to the Azure Communication Email endpoint:

Port	Description
25	SMTP port for sending emails
587	SMTP port for sending emails (alternative)
443	HTTPS port for Azure Communication Email API
