Past appointments don't use custom form

[Borat]

Hi all!

Again I have a problem with a custom appointment. Although there were no
software-updates afaik, since a few days I can't open past
calendar-entries made with the custom form (Outlook uses the
standard-appointment-form). New appointments are no problem, I can
create and edit them. Surely the form is installed and it is the
standard-form for this calendar.

Thanks
Borat

Making a form the default for a folder affects only new items, not existing ones. 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.
