Hello Sue,
Thank you for the information; I found where it can be deleted, but have not
yet, now that you have given me more to read and possibly "play" with. :-)

The "locked on Read-Only" means that, when I look into the properties of the
text box automatically created when I added the Conversation field, "Read
only" is checked and grayed out. My goal is to find out where the data
displayed in this field is taken from and if it is possible to modify it. I
found it in a columned-format view of the calendar and the data that appears
in it is rather odd... I would like it to be uniform, so it can be useful.

I did visit the other forum down the hall from you, but thus far just
subscribed to it, and will begin treasure hunting there soon. Thank you
again.

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
