I had a primary account and then a secondary account linked. Which meant i only needed to login to the primary to view the secondary's mail. However since moving to outlook.com i've lost the ability to view the secondary account and also cannot login to the account.

The automated account retrieval system doesn't recognise my details as its been so long since i used the account.

How can i recover the account?, is there a phone number i can call?.

I'm based in the UK.

Thanks in advance.
