Good Afternoon.

Theoretically, if you disable events at the start of the code and enable them again at the end of the code, you will not receive the New Mail Notification. I have not tried this yet, since it means accessing an EMail Server I don't have access to at the moment.

[VBA]
Application.EnableEvents = False

' Send EMail Messages.

Application.EnableEvents = True
[/VBA]

Let me know if this works.
