.From is not a valid argument... Outlook will attach the account email
address as from automatically. It will not show up on an email until it is
actually sent, so if you use the .display or .save arguments you will not see
a from on the email yet.
If I am not mistake, this is a security feature, it would be a bad thing if
someone could automate email to be sent on your behalf but make it look like
it is coming from somone else.
That is my knowledge, I have been working with Outlook and Excel for some
time and the one thing I still cannot get to work properly is to get excel to
open outlook if it is not currently opened.
I hope that helps.
