I created a new outlook.com email address for my daughter (9), then was asked to verify the account thru my (adult) Microsoft account. I tried this multiple times now over the last few days and only get an error message. I get to log in with my  own MSFT account, then add the credit card for the verification charge, then get an error message "we are unable to complete your request"...  anybody else has this problem?

@Microsoft support...can you help to verify this account in another way?

thx!
