Live, MSN out-of-print mailbox registration tutorial

1. Register an Outlook account first. (Select the United States as the region)
In this step, I registered directly and verified it with a US number.

2. Register an alias email: https://account.live.com/AddAssocId

3. Open the console in Google Chrome:
Select outlook.com in the input box. Look up for a label with ID SingleDomain

Modify value to:live.com

4. Enter aaa (optional) in the input box; then add an alias. (That is, submit normally)

5. Look for the tag with ID SingleDomain again.
Copy its value (the system automatically encrypts live.com into ciphertext.)

6. Open the console in Google Chrome:
After selecting the input box, outlook.com finds the tag with ID idSingleDomain.

Add attribute: value="the ciphertext of live.com just copied"

Finally, just enter the name you want to register normally.
