Yes, it's possible, but not a supported operation. Write a Public procedure in your ThisOutlookSession module to launch the userform. You can then call that procedure from your custom form's script with Application.My_Procedure_Name.

Hello everybody,

I apologize for my english, but it's not my mother's tongue.

I've created an UserForm in VBA (Outlook 2003). It's an userfom like the
one that is lauching when you click on the "Categories" button, but with
my personnal list of item (just a little window, with a liste of item to
choose).

I want to know if it is possible to launch this Userform from a customised
form : I would like to add a button to my form that will launch this UserForm.
Is it possible, and if yes, how ?

Thank in advance, and sorry again for my english.
Sincerly,
Tof
