If you use Outlook 2007 on Windows 10, you might sometimes notice that your emails get stuck in the Outbox and never send. This problem can be frustrating, especially if you need to send important messages quickly.

Fortunately, there are several simple steps you can follow to fix this issue. Most of these steps do not require advanced technical knowledge and can be done easily at home.

This guide will walk you through the basic solutions to help you get your Outlook 2007 sending emails again without delay. Just follow each step carefully.

By the end, you should understand why messages get stuck and how to prevent it from happening in the future.

Quick Note

Before starting the troubleshooting process, please check the following:

• Make sure your computer is connected to the internet. Without an active connection, Outlook cannot send messages.
• Verify that your email account settings in Outlook 2007 are correct, including your username, password, and server information.
• Ensure that Outlook 2007 is not running in Offline mode. Messages won’t send if Outlook is set to work offline.
• Check if your antivirus or firewall software is blocking Outlook’s outgoing emails.

Step 1: Check Outlook’s Offline Mode

Sometimes, Outlook accidentally switches to Offline mode. When this happens, emails will stay in the Outbox and won’t be sent until you go back online.

1. Open Outlook 2007.
2. Look at the bottom right corner of the Outlook window.
3. If you see the status “Working Offline,” click on the File menu at the top.
4. Click on Work Offline to toggle it off. The status should change to “Connected.”
5. Try sending your email again.

Why this matters: Outlook must be online to send emails. Offline mode prevents sending but allows you to compose messages.

Step 2: Review and Fix the Email in the Outbox

An email may get stuck if it is too large or contains attachments that Outlook cannot send properly. Also, corrupted emails can block the Outbox.

1. Go to the Outbox folder in Outlook 2007.
2. Open the email that is stuck by double-clicking it.
3. Check if the email has large attachments (over 10 MB) or any unusual content.
4. If the attachment is too large, try removing or reducing its size.
5. After making changes, click Send again.
6. If the email seems corrupted, delete it and create a new message.

Why this matters: Large or corrupted emails often cause Outbox issues because Outlook cannot process or send them properly.

Step 3: Clear the Stuck Message by Restarting Outlook

Sometimes Outlook gets stuck because of temporary glitches. Restarting the program can clear these problems.

1. Close Outlook 2007 completely.
2. Wait for about 30 seconds to ensure Outlook fully shuts down.
3. Open Outlook again.
4. Check if the message is still in the Outbox.
5. If it remains, try resending it.

Why this matters: Restarting refreshes the program and can clear temporary blocks that prevent sending.

Step 4: Increase Server Timeouts

If your internet is slow or the mail server takes longer to respond, Outlook might time out before sending the message, causing it to get stuck.

1. In Outlook 2007, click on Tools in the menu bar.
2. Select Email Accounts.
3. Choose View or change existing email accounts and click Next.
4. Select your email account and click Change.
5. Click on More Settings.
6. Go to the Advanced tab.
7. Find the Server Timeouts slider and move it to a longer time, such as 5 or 10 minutes.
8. Click OK, then Next and Finish.
9. Try sending your email again.

Why this matters: Increasing server timeouts gives Outlook more time to communicate with the mail server, reducing chance of failure.

Step 5: Disable Add-ins Temporarily

Some Outlook add-ins can interfere with sending emails. Disabling them temporarily helps identify if they cause the problem.

1. Open Outlook 2007.
2. Click on Tools > Trust Center.
3. Select Add-ins on the left panel.
4. At the bottom, next to “Manage,” choose COM Add-ins and click Go.
5. Uncheck all add-ins to disable them temporarily.
6. Click OK and restart Outlook.
7. Try sending the email again.

If the message sends successfully, re-enable add-ins one by one to find the culprit.

Alternative Option: Use Outlook’s Safe Mode

Starting Outlook in Safe Mode disables add-ins and customizations automatically, which helps identify if extensions cause the Outbox issue.

1. Close Outlook 2007.
2. Press Windows + R keys to open the Run dialog.
3. Type outlook.exe /safe and press Enter.
4. Try sending the stuck messages again.

If emails send successfully in Safe Mode, an add-in is likely causing the problem.
