Hi,
Please find below a similar thread

You can do some things, but you are limited in what you can do, because so much of the OWA GUI content comes from compiled code.  There is usually an .aspx page for each screen, containing plain HTML code (which you can modify, if you're careful) mixed with function calls that produce the actual data displayed (which you can't - it comes from compiled libraries).

Regarding your specific requirement, there should already be a Check Names function available on the new message screen.  Unless you're thinking of something slightly different?

Hi,

Actually in OWA, there is a button named check name will check if the email address exists or not in address book
