Hi All,

I need one macro like this; When i write a new email to a specific person, macro must add prefix text to the subject line.

For Example:
Receiver email is : (macro must work for only this receiver)
Subject is : test12345

if i click to the send email, macro must change the subject line like this : "Demo - test12345" then send the email.

is it possible?

Yes, it is possible. It's easiest to do it when the message is sent - because you'd need a macro to open the message, address it and add the text to the subject.
