There are several reasons why your Outlook might be experiencing this issue, ranging from simple configuration errors to more complex network problems. This article will delve into the common causes and provide solutions for fixing the "Outlook does not send mail" problem.
Common Causes of Outlook Sending Problems
Let's explore some of the most frequent reasons why your Outlook might not send emails:
1. Incorrect Account Configuration:
- Ensure that your Outlook account is properly configured. Double-check your email address, password, and incoming/outgoing server settings.
- Make sure your server settings are correct. You may need to contact your email provider to verify these details.
2. Outdated Outlook Version:
- An outdated Outlook version can cause compatibility issues and sending problems. Consider updating to the latest version for optimal performance.
3. Network Connectivity Issues:
- Verify your internet connection is working correctly.
- Try sending an email from a different device or browser to confirm if the problem is with Outlook or your internet connection.
4. Outbound Server (SMTP) Issues:
- Ensure that the outbound server (SMTP) settings are correct and that the port is open.
- You might need to contact your email provider for specific SMTP details.
5. Email Filters and Rules:
- Check your Outlook email filters and rules to see if they are blocking outgoing messages.

- Check for any limitations and make sure you're not exceeding them.

- Consider using a file-sharing service or compressing the attachments to reduce their size.
