I have an outlook.com email address which is not linked to my existing 365 subscription. I want to link it but have been able to do so. Can it be done and how to do it. Thank you.

Hello

If you already have a 365 subscription, it means it is already on an existing Microsoft account.

Here is a problem, an "existing" outlook.com address cannot be added to another existing Microsoft account. It is not supported.

Microsoft explains it here: https://support.microsoft.com/en-us/office/add-or-remove-an-email-alias-in-outlook-com-459b1989-356d-40fa-a689-8f285b13f1f2
