Help … Outlook.com Primary and Alias Account Swapping. Using Bell Canada “Sympatico” account provided by Microsoft.

I have had MS email accounts since the late 90's and Hotmail.  Years ago internet providers assigned email accounts to people with their monthly contracts for free.  Bell Canada accounts were all ###@sympatico.ca .  A few years later, Bell switched to have Microsoft provide the email services first through the Hotmail services and now through the Outlook.com service but have retained the sympatico.ca email addresses.  I currently log on to Outlook.com using my ###@sympatico.ca account.

My concern is now that I have invested in a Windows Phone, a Windows Tablet and my windows 8 desktop, which all are linked to my ###@sympatico.ca account,  when I move next year ( I move often in the military) if I do not stay with Bell as my internet service provider I will loose access to all of the cloud services and email including my skydrive associated with my account.

I have created an alias account that is linked to my primary outlook.com account and have gone through the settings to swap the alias and primary accounts but the button is greyed out for my sympatico.ca account and can't be clicked.

I no longer want to be tied to Bell Canada's account through Microsoft but I want to keep all of my existing Cloud accounts and purchase history.  I have tried to do the opposite and create a new outlook.com account and add thet sympatico.ca account as a alias but outlook recognizes this as an existing outlook.com account and wants me to set it up as POP3 or IMAP forwarding instead. 

I have seen this question asked in forums before but most answers fail to see that the sympatico accounts are provided by Microsoft.

Thanks for helping.
