Lock edited pdf document

[cje]

Hi, is there a way to lock an edited pdf document in xchange viewer?

I've added an extra contact information which I doesn't want to be deleted.

Thanks for any suggestions

Hi cje,

Thanks for the post - The only way to stop the document from being modified is to either sign it with a digital signature, or password protect the document:

HTH!
