but when i close new mail window of outlook & shoot same command outlook does not open.
What new mail window did you close? Is it the new mail windows created via clicking Send > Email button in Word? Do you mean this issue happens when you quit sending the Word document?
Do you have Outlook opened when clicking Send > Email button in Word?
Would you please clarify the detailed steps you used to reproduce the issue so that we can understand the issue more clearly?
