Have you considered using a custom text field and text box instead of the regular message control?

I am designing a simple form in outlook I plan for people to use to send me
an SMS text message to my cell phone. The message field field is set to
unlimited length. That means I get several messages from the person, because
my phone is limited to 160 or so characters per message.

What I want to do is Outlook/Exchange to limit the form to that many
characters, so they can't send a message longer than my phone can fit into
one message.

Thanks!
