If you published it to a folder, then you should be able to delete from that folder's Properties dialog, using the Manage button on the Forms tab.

To change existing items so that they display using a published custom message form, you need to change the value of the MessageClass property on each item so that it points to the published form's class, e.g. IPM.Contact.MyForm. The page at http://www.outlookcode.com/article.aspx?id=39 has links to scripts and tools to do this.

I don' t know what you mean by "locked on Read-Only"

FYI, there is a newsgroup specifically for Outlook forms issues "down the hall" at microsoft.public.outlook.program_forms or, via web interface, at http://www.microsoft.com/office/comm...rogram_f orms

When I look in Forms... Choose form... it appears in Calendar and in
Outlook Folders. I had modified the Appointment form by adding the
Conversation field and saved it with a different name, but it does not apply
to pre-existing appointments, and besides, it's locked on Read-only.

Hi,
How can I delete a form I created as a modified copy of the Appointment
form?
