Why are no emails sent in Outlook

Outlook: no email reception - what to do?

If you cannot receive email with Outlook, there are three places where you can troubleshoot. We will show you how you can exclude sources of error and try out solutions.

Check email server

If sending and receiving emails doesn't work, Outlook doesn't have to be the problem. Check whether you can connect to your e-mail service via your browser:

  1. Go to your email service website. If the page does not load, all you have to do is wait and see, as the problem seems to be with your email provider. Perhaps these practical tips about GMX will also help you in this case.
  2. If the page can be called up, log in. If this doesn't work, your data is probably incorrect or your account has been blocked. In this case, contact customer service. For example as described here for GMX.
  3. If the log-in works, you at least have an emergency solution for sending and receiving e-mails. In this case, check your Outlook settings.

Outlook settings for sending and receiving

In Outlook itself there are a few settings that you can change if you have problems.

  1. Press [F9] to send and receive emails.
  2. Navigate to Tools> Email Accounts> View or Edit Existing Email Accounts and click Next.
  3. Select your e-mail account and click on "Change ..." and then on "Additional settings ...".
  4. Compare the data entered here with the specifications of your e-mail service. You can find this on the website of your e-mail service or in this or that list. Instructions for T-Online can be found in this practical tip.
  5. Many services, such as Gmail, offer extensive support. Here you can find alternative ports for SMTP, for example, which you can enter and try out under the "Advanced" tab.
  6. Standard ports for SMTP are "25" for TCP, "465" for TCP with SSL / TSL encryption and "587" for TCP for delivery by mail clients. The port for POP3 is usually "995" and for IMAP "993".
  7. If no emails are still being sent or received, the last thing you can do is to check your firewall settings

Check Outlook internet connection

If sending and receiving do not work, Outlook may be blocked by your firewall.

  1. Open "Run" with [Windows] + [R] and enter "cmd" in the input window.
  2. Now type "netstat -b". A list of connection calls appears.
  3. If you are not an administrator, you can use these instructions to generate the command as a batch file and then execute it as an administrator.
  4. If "Outlook.exe" does not appear under "Active Connections", Outlook may be damaged and can be repaired with a new installation.
  5. If "Outlook.exe" appears but is displayed as "Waiting", your firewall is probably blocking the connection to the Internet.
  6. Unblock or temporarily disable it in your firewall. We offer instructions for Avast and Windows 8.
  7. Here you can find general help if Windows 8.1 apps cannot connect to the internet.
