It was set to default to *** Email address is removed for privacy *** (Primary Alias). So i added *** Email address is removed for privacy *** sucessfully again, and hit (make my primary alias) After i did that, it mentioned to give it 48 hours to fully replace all info etc. 

So, I tried to go back to my inbox to sort out emails and i encountered a page saying

(TRY TO RETURN TO OUTLOOK)

And hasn't changed since. Been about 12 hours. Do i really have to wait 2 days? I've tried sending emails from my gmail account and i get a SMTP 5.1.1 error each time. (Diagnostic-Code: smtp;550 5.1.1 Mailbox USER does not exist.
