MSGTAG and Outlook

All you have to do is make sure your SMTP server in Outlook is set to localhost, and take your SMTP settings from Outlook and add them into MSGTAG - this is how the mail gets put through MSGTAG on your desktop, and how the tag is added.

We've added screenshots below to take you through the whole thing, in case you haven't checked your settings in Outlook before. Note that it should be your details entered rather than those shown in the screenshots, and that the pictures are taken from Outlook version 10.x on Windows 2000. Things may be a little different, but it's all pretty much the same. If you don't know your SMTP server settings, please ask the person in charge of IT at your company, or your Internet Service Provider. Can you also ask them what sort of mail server you use? If it's a Microsoft Exchange server, then MSGTAG won't work for you.


  1. Go to Mail Accounts

  2. Select the account you wish to check

  3. Check that the SMTP settings for the mail account are correct.

    • In SMTP server name, insert the name of your local SMTP server. Your ISP or the IT person at your company can provide you with this. Contact them if you are unsure what this is.
    • The SMTP server port is nearly always 25. However, check with your ISP or the IT person at your company to make sure.
    • Set the Listen for SMTP connections on port to 7362. This number will have to be entered into Outlook later.

In Outlook:

  1. To check your settings in Outlook, start Outlook and go to the Tools menu and choose E-mail Accounts.

  2. Select View or change existing e-mail accounts and click on the Next button.

  3. Highlight the account you want to view and click on the Change button to see the E-mail accounts window.

  4. Check that the Outgoing mail server (SMTP): is set to localhost and then click on the More settings button.

  5. Click on the Advanced tab.

  6. Check that the Outgoing server (SMTP): is set to the same number that is specified as the MSGTAG listening port: 7362.

Now, open up Outlook and send yourself a test e-mail. Just write a normal e-mail and send it to your own e-mail address. Once it's been sent, wait a minute or two and then check for new mail, and you should see the e-mail you sent to yourself in your inbox. Open the e-mail and you should see a MSGTAG footer at the bottom of it. If you don't then the test has failed. If you do, then all is probably well. Wait a few minutes and click "Send/Receive" again: there should be an e-mail there letting you know that you've just read the e-mail you sent yourself. If you got the notification then you're all done!

If this doesn't work, then it's very important that you change your Outlook SMTP settings back to whatever they were, otherwise your e-mail won't be able to go out. The screenshots should help you put things back to how they were. If you get really stuck and e-mail doesn't seem to be going out at all now, then go to the contact page and send us an e-mail with the words ATTENTION URGENT at the top and then your name and email address.
