How can I change the Invite mail content?

Hi Everyone, I have a problem:

I inserted some LotusScript to ‘QuerySave’ event of ‘_Calendar’ form in the mail db. I want to use this LS to modify the ‘Body’ item of the Invite mail. But I found if I change the value(string) of the Body item in current UI document, after Notes send this document, the ‘Body’ item rollback to before value. And in the invite mail, the content is old content, I cannot add any string to it! I think maybe it cause by ‘Body’ field is a encrypt field.

Did anyone meet same problem before? Please help! Any is welcome. Thanks.

Regards,

~Eddy

Body is a rich text field; any changes you make to the back-end value while the document is open will be overwritten by the front-end editor content. If you have to add something, use FieldAppendText.
