Populating drop-down boxes from MS Access

[Sanna B]

Hi everyone.

Here's my question:

I am trying to send an e-mail questionnaire to All Users, using a
published custom form. They can fill in all the data and return to a
specified mailbox where my Access db will read and store them
automatically.

I know how to populate a drop-down on form_open of the form itself,
but that is not viable in this case, also my Exchange Administrator
does not like having too much traffic on his prescious network

So I am wondering if it could be done at the time of creating and
sending of a form. I am having a little trouble understanding the
limitations of the form manipulation from Access. I know I can add
UserProperties to the form before it's sent, but can't see how to
access form controls? Is it at all possible?

Thanks
Sanna
