Server error: '550 5.7.1 <email@example.com>... Relaying denied. IP name lookup failed [18.104.22.168]'
I then tested direct in Post Office I get the below error for any email address I try
Failure sending message: Email address not valid. Please use an email address which looks like firstname.lastname@example.org
I have gone through all settings in Outlook to ensure they are correct, and tested Post Office as I need to send an email from this account.
Thank-you for any help you can provide.
