How do I prevent an excel attachment being forwarded on by email?

[Guest]

I want to send an excel document as an attachment to an email.

I want to make two security features:

1. I dont want the recipitent to be able to edit, change or modify the data
in the workbook.

2. I dont want the recipitent to be able to forward the excel document
onward by email again.

Please advise

You could protect the workbook and put a password on it that only you know
for the first one. Another way would be to create a PDF of the document,
but you'd need to have a PDF writer and not everyone has that.

I do not know of a way to prevent people from forwarding mail that has been
sent to them.

#1. I don't think you can do it. Excel's security (tools|Protection) is not
made for this type of thing. It's easily broken. Maybe sending the report in a
different type of file, like a picture (.jpg) would be better.

#2. I don't think that this is possible with any file format.
