When using Adobe Acrobat Pro - I was trying to insert a signature and receive a Forbidden Error Message. When trying to share a pdf file I click on the envelope to share it and receive a Forbidden Error Message
p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.
