Hi, 

I have successfully added my domain in domain live.com. I'm managed to create 2 emails under my domain name. However, when I try to create 1 of the email accounts with the name of yyy@ .....    I get this error message:

A Microsoft account already exists with this account name. This was likely an account that was used before the domain was using this service.

You may import the account or you may evict this account and create a new account with this name. If you evict the account, the name may not be available for reuse for up to 60 days to protect the previous member's privacy.
