Common Issues:

I need help to setup my email account.

I have issues sending mails out to my recipients / I encountered a “We do not relay” error message. (SMTP Authentication)


1. Start the Microsoft Outlook program.

Use the Start menu to start Outlook 2016/2019/2021/Classic. (If this is the first time you are using Outlook on your device, a small window with Outlook logo will prompt you to create a new account. Please close this window by clicking on the X sign located at the top right corner of the window.)

Under the main Outlook user interface, click the File tab located at the top left corner, then the Account Settings -> Manage Profiles button.

Under Mail Setup – Outlook window, click Email Accounts button.

Under Account Settings window, click New button.

Under Add Account Window, choose the Email Account option, and fill in the necessary details. Click Next when done. Outlook will attempt to use Autodiscover to find your default POP3 account and server settings. (If you wish to skip Autodiscover or prefer to create an IMAP account, choose the Manual setup or additional server types option, and click Next. Then skip to Step 3.)

 If Outlook Autodiscover is successful, you will see the message Your POP3 email account is successfully configured. Click Finish to complete the account setup.

If Outlook Autodiscover is not successful, or the account setup takes a long time (more than 1 minute) to process, cancel the Autodiscover process by clicking the Back button. Then proceed to Step 2 for manual setup.

2. The Add Account window appears.

When this window appears, leave the spaces empty, choose the Manual setup or additional server types option, then click Next.

3. The “Choose Service window” appears.

Choose POP or IMAP, then click Next.

4. The “POP and IMAP Account Settings” window appears.

This is the window where you’ll enter most of your account settings. Be sure to choose POP3 and use the above email server information. You may refer to the image file as an example.

“Your Name” is the name that other people will see when you send them e-mail. It should usually be your real name.

Enter your “Email Address”. The address must be the e-mail address of the mailbox you created in your account management control panel.

For “Account Type”, choose POP3.

Enter both the “Incoming mail server” and “Outgoing mail server (SMTP)” as mentioned below.

5. Setup SMTP authentication settings for Outgoing mails

Under Account settings, locate “More Settings”.

Click the More Settings button. A new “Internet E-mail Settings” window appears.

6. Choose the “Outgoing Server” tab.

In the “Outgoing Server” tab, check My outgoing server (SMTP) requires authentication.

Choose “Use same settings as my incoming mail server”.

Do not leave a tick on, “Log on using Secure Password Authentication” and click Ok.

7. Choose the “Advanced” tab.

Under the “Advanced” tab, check and verify the following details:

Outgoing Mail (SMTP) port number25 or 366 (Icewarp/CPanel) / 465 (CPanel with SSL)

Incoming Mail (POP)110 (Icewarp/CPanel) / 995 (CPanel with SSL)

Icewarp Users:
Kindly take note that no SSL connection is required for both incoming and outgoing connections.

CPanel Users:
You may enable SSL connection for both incoming and outgoing connections. Please ensure you have updated the correct port settings to be used with SSL, ie 465 for SMTP and 995 for POP3.

Kindly check the “Delivery” section, do untick the “Leave a copy of messages on server”. By doing so, downloaded mails will be removed from the server thus clears the mailbox space.

Click on “OK”.

8. Close the “Internet E-mail Settings” window.

Click OK to close the “Internet E-mail Settings” window. The “Add New Account” window will still be visible.

9. Click the “Test Account Settings” button and you should see all items with green check marks.

Click the Close Button to close the test window. Click OK to save your settings.

If Outlook tells you a test failed, double-check to be sure you’ve entered the settings correctly.

10. Finish the wizard.

If the “Test Account Settings” window is still open, click Close to continue.

Click Finish to finish the wizard.
