Get help when your email messages don't send

You've sent email messages but they appear to be stuck in the Outbox. Try one or more of the following procedures to resolve the situation.

Important: If after upgrading Windows 7 or Windows 8.1 to Windows 10, Outlook fails to send email, and you receive this error: User account – Sending’ reported error (0x800CCC13): ‘Cannot connect to the network, verify your network connection or modem. For information on how to get past this issue, see Outlook Send/Receive error: 0x800CCC13 after upgrading to Windows 10.

Make sure your mail server is online

Look at the bottom of your Outlook window. You'll see the words Connected to, followed by a server type, such as Microsoft Exchange, or you'll see Disconnected or Trying to connect…

If you're disconnected, check your network cable. You might also try restarting your computer. If those steps don't work, contact your Internet Service Provider or your system administrator.

Free messages stuck in your Outbox

When a message gets stuck in your Outbox, one possible cause is a large attachment.

  1. On the Send/Receive tab, click Work Offline.

  2. On the left, in the Navigation Pane, click Outbox.

  3. From here, you can:

    • Delete the message. Just select it and press Delete.

    • Drag the message to your drafts folder, double-click to open the message, and delete the attachment (click it and press Delete).

    • Place the attachment on a file server or other location where others can get it, then add that location to your message.

  4. If an error tells you Outlook is trying to transmit the message, close Outlook. It may take a few moments to exit.

    Tip:  If Outlook doesn't close after several minutes or you see an Outlook is not responding message, press Ctrl+Alt+Delete and click Start Task Manager. In Task Manager, click the Processes tab, scroll down to outlook.exe, and click End Process.

  5. After Outlook closes, start it again and repeat steps 2-3.

  6. After you remove the attachment, click Send/Receive > Work Offline to deselect the button and resume working online.

    Tips:  Messages also get stuck when you click Send but you're not connected. Click Send/Receive and look at the Work Offline button. If the button is shaded, click it to connect (this also unshades the button), and then click Send All.

If you use Office 365, make sure you're logged in

  • Make sure you're logged in with your Office 365 user name and password. For example: Don't try to use network credentials such as contoso\jbarnhill.

  • If you're logged in and you still have a problem, wait a few minutes and try again.

Make sure you're using the right password

If you change the password on an Internet mail account, be sure to change it in Outlook, too.

  1. On the File tab, click Account Settings > Account Settings.

  2. On the E-mail tab, click your Internet mail account and click Change.

  3. Enter your new password in the Password box.

  4. Click Next.

  5. After Outlook tests the connection, click Close > Finish.

Note:  If you log on to your mail account with the same credentials you use to log on to your network, you won't see the screens shown here. You'll have to change your email password by changing your network password. To do that, press Ctrl+Alt+Delete, click Change a Password, and follow the instructions Windows provides.

Make sure you've configured an email account

If you can't see the Send button in Outlook, chances are you need to configure an email account.

  1. On the File tab, click Account Settings > Account Settings.

  2. On the E-mail tab, click New. That starts the Add Account wizard.

  3. On the first page of the wizard, make sure E-mail Account is selected and click Next.

  4. On the next page, enter your name, email address, and your new password in each box, then click Next.
