My manager Stanley uses adobe acrobat 8 and an e-certificate to approve purchase requests, he receives these via email. He is using Microsoft Office 2010 by the way. When he reviews the form and approves it he attaches a digital signature to it as proof of approval and sends it to accounting. This was done where he would start by forwarding the email then editing the attached adobe form. This would allow for the edit to automatically save back into the email revising the attachment and not requiring to save the file somewhere and having to reattach it. Since he got an update this no longer works just for signed forms (text edits on the form can be saved back OK). Do we need to create a new signature, and how can we resolve this?
It looks like the certicate has has expired. I need to create a new signature.
