How Do I Fix Outlook Not Sending Emails – Fixes to Try

If MS Outlook isn’t able to send emails, you need to configure its settings. Go through the various troubleshooting steps that you can try when your messages get stuck in the outbox.

Resend your message

When you can’t send emails from Outlook, the best thing you can do is resend your message. Do the following.

Right-tap the email that’s stuck in your outbox and point it to ‘Move.’ Select the ‘Drafts’ folder.
Open that email and tap ‘Send.’
See if the mail has landed in the sent folder. Most probably, it will be sent.

Ensure that you work in online mode

You can work either offline or online mode in Outlook. If you find your mail stuck in the outbox and not in the sent folder, check whether your status is online. You can check it in Outlook 2007 as follows:

Launch MS Outlook.
Tap the ‘File’ tab.
See that there isn’t any checkmark against ‘Work Offline.’
If there is, tap it and remove the checkmark.
Now that you are working online tap send and receive again to send the messages in your outbox.

See your recipient’s email address.

The problem of Outlook not sending emails can also arise when there is an address conflict between the saved address and your email address. If the address is not present in the address book, you need to add it there. It can help you resolve your issue by sending your email.

Check Outlook’s Send options.

You also need to ensure whether the send options in MS Outlook are right or not. Follow the instructions below for checking these options.

Launch Outlook.
Tap on the tab of ‘Tools.’
Choose the tab of ‘Mail Setup’ or the tab of ‘Send’ according to the MS Outlook version that you are using.

Inspect your internet connection settings to make sure that your laptop or personal computer is firmly linked to your internet provider.
Return to the outbox folder. Open your email and then tap ‘Send’ once more.

Check your attachments

Outlook restricts the file size that you can send in emails to 20 megabytes. 20 megabytes is for internal accounts like Hotmail or Gmail, while 10 MB is the size limit for Exchange accounts. So, when Outlook is not sending emails, you need to look at the size of your files. If you encounter an error message concerning the file size when you send an email, you can increase the limit for Outlook.

For it, launch the ‘Windows Registry Editor’ and then locate the entry for Outlook. Then modify the value of ‘MaximumAttachmentSize.’ Now you can input the preferred size limit. It should be in KB. Note that the file size limit cannot go beyond the limit of your mail server.

Now, choose ‘Next’ and then ‘Close.’ Then tap ‘Finish.’
Choose the button of ‘Send/Receive All Folders.’ You can find it in the upper-left part of the Outlook window. Alternatively, you can tap ‘F9’ to send your email.
