Answer 1

Hi @William Taylor

Thank you for reaching out and sharing your question with us. I understand you're encountering issues while trying to send emails from a group email address using an Azure Function, and I appreciate the challenges these limitations may cause for your communications. 

After reviewing the current configuration and available documentation, we found that Azure Communication Services (ACS) requires the sender email address to be fully verified. This process relies on domain authentication methods such as SPF and DKIM, which apply only to individual email addresses. As a result, group email addresses or distribution lists are not currently supported for direct verification. 

If you're trying to send emails from a group address like ******@yourcompany.com, the first crucial step is to ensure that your domain (e.g., yourcompany.com) is properly added and verified in your ACS resource. You may need to set up essential DNS records (SPF, DKIM, DMARC) to allow sending from this domain and ensure good deliverability. 

Since a group email address cannot be directly verified as a sender, we recommend the following alternative: 

• Use a Dedicated Mailbox as the Sender: Consider using a dedicated, verifiable individual mailbox (for example, ******@yourcompany.com) as the actual sender in your Azure Function. 
• Set the Group Address in the Reply-To Field: To ensure replies from recipients go to your desired group, you can set your original group email address (e.g., ******@yourcompany.com) in the Reply-To field of your email. This directs replies back to your group without that group address being the direct sender from ACS. 

Alternatively, if you're exploring broader use cases beyond ACS for example, within Microsoft 365, you may consider configuring Send As or Send on Behalf permissions for the group mailbox. This can provide more flexibility when using group identities for communication. You can find more details here:  Allow members to send as or send on behalf of Microsoft 365 Groups 

For more detailed, step-by-step instructions on configuring sender identities and managing verified domains with ACS, please refer to the following official documentation:
