How to Fix 'Message Cannot Be Sent Right Now' in Outlook

If you’re encountering the error message “Message cannot be sent right now” in Outlook, it can disrupt your workflow and delay important communications. This guide provides clear, practical steps to troubleshoot and resolve this issue so you can send emails smoothly again. Before starting, ensure your internet connection is active and stable, as connectivity issues are often the root cause of email sending problems.

What You’ll Need

Computer or device with Outlook installed
Active internet connection
Access to your Outlook account credentials
Optional: Administrator access if making system or network changes

Step-by-Step

Check Your Internet Connection: Make sure your device is connected to the internet. Open a browser and visit a website to verify connectivity. A weak or unstable connection can prevent Outlook from sending emails.
Restart Outlook: Close Outlook completely and reopen it. Sometimes, a simple restart can resolve temporary glitches causing the message error.
Verify Your Email Server Settings: Ensure your account settings are correct. Go to File > Account Settings > Account Settings, select your account, and click Change. Check the server addresses and port numbers against your email provider’s recommended settings.
Clear Outbox and Resend: Navigate to the Outbox folder. If the stuck message is there, delete it or open it and try resending. Sometimes, a corrupted email can block the queue.
Disable Offline Mode: Ensure Outlook isn’t set to Work Offline. Go to Send/Receive tab and click on Work Offline to toggle it off.
Check for Large Attachments: Large files can prevent sending. Reduce attachment size or upload files to cloud storage and share links instead.
Update Outlook: Outdated software can cause bugs. Go to File > Office Account > Update Options > Update Now to ensure you have the latest version.
Disable Add-ins: Faulty add-ins may interfere. Go to File > Options > Add-ins, manage COM Add-ins, and disable suspicious ones. Restart Outlook and try again.
Check Your Antivirus and Firewall Settings: Sometimes, security software blocks email sending. Temporarily disable them to test if they are the cause, then re-enable after testing.
Repair Outlook Data Files: Corrupted data files can prevent sending. Use the Inbox Repair Tool (scanpst.exe) to scan and repair your PST files.
Contact Your Email Provider: If issues persist, reach out to your email provider for server status or specific configuration guidance.

Common Mistakes

Ignoring internet connectivity issues – always verify your connection first.
Trying to resend emails with large attachments without resizing or compressing them.
Disabling antivirus or firewall without understanding their impact on email security.
Updating Outlook without backing up your data, risking data loss.
Assuming the problem is on Outlook’s side when it might be a server or network issue.

Tips

Regularly update Outlook to prevent bugs and compatibility issues.
Keep your device’s operating system and security software current.
Use cloud storage links for large files to avoid attachment size limits.
Check your email server status periodically, especially if multiple users report issues.
Maintain a clean Outbox by deleting or resending stuck messages periodically.

If these steps do not resolve the problem, consider the following troubleshooting options:

Test on a Different Network: Switch to a different Wi-Fi or mobile network to rule out network-specific issues.
Create a New Outlook Profile: Sometimes, corrupt profiles cause sending issues. Go to Control Panel > Mail > Show Profiles to create a new one and set it as default.
Reinstall Outlook: Uninstall and reinstall the application to fix corrupted files or installation issues.
Check for System Updates: Ensure your operating system is up to date, as system bugs can affect Outlook.
