Email message not delivered

Hi @Vinod Vanga

Based on the information you provided, I understand that you are encountering the message "This message has not yet been submitted for delivery" when trying to send an email from Dynamics 365. This essentially means the email is stuck in an internal "Pending" state within Dynamics and hasn't been handed over to the mail server (like Exchange or Gmail) yet.

This error usually points to a configuration gap in the Mailbox or the Server Profile. Common causes include:

-The Mailbox hasn't been Approved or Enabled by an admin.

-The Outgoing Email Status is set to "None" or "Not Run."

-The Server-Side Synchronization is failing or configured incorrectly.

Please try the following steps to identify where the connection is breaking:

1. Check the Mailbox in Power Platform Admin Center

Go to: admin.powerplatform.microsoft.com > Navigate to Environments > [Select your Environment] > Settings > Email > Mailboxes > Open Active Mailboxes and search for the user or queue in question > Check for any Alerts, Errors, or Warnings in the top ribbon or the side panel.

2. Verify Outgoing Email Status

Inside the Mailbox record, look at the General tab > Check the Outgoing Email Status. If it says "Not Run" or "None," the email will never leave Dynamics. This indicates the system hasn't successfully tested the connection to the mail server.

3. Verify the Server Profile

Check which Server Profile is being used (e.g., Exchange Online, Gmail, or a custom SMTP). Ensure the profile is Active and the settings (Server-Side Synchronization) match your mail provider’s requirements.

4. Approve and Enable the Mailbox

Even if the settings look correct, an admin must: Click Approve Email (top ribbon) > Click Test & Enable Mailbox > Wait for the test to complete. If the "Outgoing Email" status doesn't change to "Success," the email will remain in "Pending Send" indefinitely.

Please be aware that Microsoft Dynamics 365 products are currently not supported in the Microsoft Q&A forums. For this specific scenario, I highly recommend posting your question in the Microsoft Dynamics 365 Community . The subject matter experts there can provide more detailed technical guidance.

I apologize for the inconvenience, and I hope these steps help you get your emails moving again!
