Cannot connect to Microsoft Online Hosted Exchange with CFMAIL

Hi

I work with a non-profit in northern California that facilitates high-tech internships for teachers.

While their site host is Hostmysite.com - they recently moved their email services to Microsoft Online's hosted Exchange services.  As such, I need to update their code to send email notifications off of their new exchange servers so email dont appear as spoofs.  '

Microsoft provides the following settings:

I've set my cfmail tag as such - however, regardless if I use useTLS, useSSL or both, the emails are not sent.  A quick review of the CF mail log file reveals:

"Error","scheduler-1","04/14/10","14:47:00",,"Could not connect to SMTP host: smtp.mail.microsoftonline.com, port: 587"

<cfmail server="smtp.mail.microsoftonline.com"

username="web@***.org"

password="********"

useTLS="true"

port="587"

subject="Hello World"

to="****@yahoo.com"

from="web@***.org">

This is my test email - did it work?

</cfmail>

Any ideas?  Your help is appreciated!

Ben
