With the purchase of a windows 8.1 home laptop I wanted to change the primary alias on my microsoft account from a hotmail.com (my work email) to a gmail account (my home email.) As microsoft accounts are now tied to the login screen.  

Now it won't allow me to add my hotmail.com as a secondary alias and I can't find a way to access my account. The error message I receive reads -
'You can't add an alias with the domain hotmail.com. Try an email address that has a different domain.'

Losing access to my work email is a huge deal for me and I don't know how this could have happened just be removing an 'alias'. What is going on?

My phone's outlook app won't recognise my gmail or hotmail account so access is completely denied there.

Going to outlook on the browser now only logs in with my gmail. 

I have lost my emails and my email id. Please help me recover this.
