I'm using Windows Live Custom Domains for my organization wich locates in Indonesia. My domain is gafatarjateng.or.id. By default, Outlook.com account currently will not let my user send email without verifying the account.  All my created users, when  attempt to verify the account by entering mobile phone number, "Indonesia" option does't exist in the list. 
Can you help, please?
