where is my eMail actually sourced?

I am a new user to outlook.com -- but reasonably experienced in eMail in general.

I've recently been asked to help manage our "custom domain" -- centralrockgym.com (esp. the eMail and SkyDrive organization)

My initial task was to find our current eMail users and that is how I encountered this question.

To this end, I discovered 45 names listed under our "custom domain".

However, even though my email address is "*** Email address is removed for privacy ***" I do NOT find myself in that list.

Could it be that my eMail account was created within the "centralrockgym.com" domain but is not in our "custom domain"?

I say this because I can access the account using 'outlook.com' (on web, on my Android, etc.).

However, I am confused as to why I would not see it in that list of 45 eMail users in the custom domain.

So, the QUESTION: where is my eMail account actually 'sourced'?

ADVthanksANCE,
