Hi @Philip Samson ,
How did you add configure your account? Do you refer to this link? https://www.kcom.com/home/help/broadband/how-do-i-setup-my-email-on-outlook-2016-or-outlook-365/ (Note: Since the web site is not hosted by Microsoft, the link may change without notice. Microsoft does not guarantee the accuracy of this information.)
In addition, I suggest you contact your email provider to see if it is applicable to other versions of outlook clients.
