I think the mailbox that you used is an Office 365 mailbox rather than Exchange on-premises mailbox.

To narrow down it, I would confirm below information about you:

  1. Do you use a hybrid environment? Whether is this mailbox an Office 365 mailbox?

  2. Hold "Ctrl" and click Outlook ICO, then check the "Connection Status" (You can post the result after removing domain name)

  3. You can also use "Test Email AutoConfiguration" to check the connection process
