Outlook doesn’t use email addresses to route e-mail with Exchange servers. Instead it uses some internal “address” that is longer than the actual e-mail address.
This becomes a problem when an e-mail account is deleted and then recreated later. And the old internal address is still in some users Outlook addressbook. Because the internal address changes when the account is recreated.
