Hello, thanks for the reply.

I tried your code, executing it step by step, it send the mail correctly but without any message. Anymore it sends the mail at the line
The source active document is the body message that I have to send. After that the code will active other word document that contains information about mail destination and attachment directory.

I don't want an exact format word format in the mail, but I need to enclose bold formatting, colour formatting and some image.

If I try the mail merge without attachment (from word utilities) it gives me back a good formatted mail. I'd like to obtain a format like this.. Could it be possible?

Thanks a lot
