Exchange email sent from a shared mailbox stuck on Outbox folder with error

One common issue that users face in Microsoft Exchange is when emails sent from a shared mailbox get stuck in the Outbox folder, often accompanied by an error message. This situation can be frustrating, especially if the emails are time-sensitive or critical for business operations.

Problem Scenario

You may encounter a situation where you attempt to send an email from a shared mailbox and it becomes stuck in the Outbox folder with an error message that prevents it from being sent. Here’s a simplified version of the problem:

Original Code for the Problem:

Email stuck in Outbox folder
Error: "Cannot send the message. The mail server responded: <error message>"

Understanding the Problem

When an email is stuck in the Outbox, it typically indicates a failure in sending due to various reasons. These reasons can range from network issues, improper configuration of the shared mailbox, permission problems, or even the size of the attachment being too large.

Common Causes and Solutions

  1. Network Connectivity Issues:

    • Cause: The most common reason for emails getting stuck in the Outbox is a weak or interrupted internet connection.
    • Solution: Check your network connection. If it seems unstable, reconnect to the internet or switch to a different network.
  2. Permissions for Shared Mailbox:

    • Cause: You may not have the right permissions to send emails from the shared mailbox.
    • Solution: Verify that you have been granted ‘Send As’ or ‘Send on Behalf’ permissions. An administrator can check and modify these settings.
  3. Outdated Outlook Client:

    • Cause: Sometimes, bugs in older versions of Outlook can lead to issues in sending emails.
    • Solution: Ensure that your Outlook client is updated to the latest version.
  4. Email Size Limitations:

    • Cause: Attachments that exceed the server's size limit can lead to errors.
    • Solution: Check the size of the email. If it exceeds the limit, consider compressing the attachments or using file-sharing services.
  5. Corrupted Outlook Profile:

    • Cause: A corrupted Outlook profile can also cause issues.
    • Solution: Create a new Outlook profile and set up the shared mailbox again.
  6. SMTP Configuration:

    • Cause: Misconfiguration of the Simple Mail Transfer Protocol (SMTP) settings can prevent sending.
    • Solution: Double-check the outgoing server settings and ensure they are configured correctly.

Practical Example

Imagine you are in charge of a project that requires urgent communication with team members. You draft an important email to share project updates using a shared mailbox but find that the email remains in the Outbox.

By checking your network, you notice that your Wi-Fi has been disconnected. Upon reconnecting, the email sends successfully. This simple troubleshooting step illustrates the importance of network reliability when sending emails from shared mailboxes.
