Hi

I have an absence custom form in Outlook 2003. This form will be installed
by an add-In. It is visible at the appointment definition form. When i open
the form i get an error message "Error displaying the fields of the absence:
Invalid class string"

The form has as content an ActiveX control that set a few user properties at
the appointment.
At the environment where I have the problem is a special behavior(Perhaps it
has something to do with the problem). When I open the form Designer
Extras-Forms-Design a form select the "Lib for personal forms" and open my
form, i get a popup that wants an password.

In my opinion it has something to do with the security. Does anyone has a
hint for me, to solve this problem?

Regards Thomas
