TW33K, I don't know who you are, but thank you!
I've been bitten by the change in behaviour with Outlook 2010 with the default account that's used to send e-mail. This macro has brought back the functionality that I need.
I recognize that some may see the 2010 functionality as better, some may see it as worse, some may see it as a bug. In my eyes, I see it as a change and can understand why different people would want to see it behave differently. This Macro is extremely helpful!
With luck a future update to Outlook 2010 will provide options for how the behaviour works. Until then I have my new mail button that works as expected!
Cheers,
