yes, outlook 7.0 supports and recognizes idn@idn.idn, which also receives IDN@idn via pop3.
But it can not support the sending of  idn@idn.idn via SMTP.

Outlook client for windows does support and recognize idn@idn.idn Cyrillic email
It doesn't fly with hotmail / outlook web email though.

Hello,
 
     Is there any news about Microsoft outlook's support of idn email ?
     I heard that Microsoft will support it, but do not know the time table.
 
    thanks.
