Actually I have two live mail account and I want to make another account sync with my window phone. Can anyone tell me what do I do? There is no option to delete main account from email+account.

You can't change the main account without erasing the phone. I would add an Outlook.com account since it uses the same stuff under the hood as hotmail, Live and outlook.com

You have to do a factory restore. there is NO ability to switch the account after it is initially setup.

They are correct, you can not switch accounts for the over all phone without first doing a factory reset and erasing all existing data. You will not be able to transfer owned apps. You will have to purchase them again.

As stated also, you can just add the email account.

what about aliases??

The following way (I've tried) can solve the issue:
1) Change the password of your Microsoft account by signing in the website live.com.
After doing this, the MS account on your WP mobile shall be automatically signed out.

2) Now you can sign in with another MS account on your WP mobile.

That's all!
