I have a workflow that is built in Nintex. It is a message for notification that an approver needs to electronically sign a PDF document from SharePoint. When I access the document directly from SharePoint, it opens in PDF. However, when I access it through the email message from the Message notification, it opens the document in a browser, not enabling someone to sign the PDF using their credentials. I have added a work around where it takes the user to the library to access the form, but would like the user to access the document from the link that is pulling the Item URL. I perform the original action using a Word document where it opens it up in Microsoft Word, but the PDF document won't. Thoughts?
