Is this a situation where they want to print ONE PO at a time and e-mail it??? If so, while there are a couple clicks involved, here is what I recommend..
Quick Print
Preview the form in Crystal.
Export Report
Choose Adobe Reader/Application
After Adobe opens, click on the envelope icon to share as an e-mail attachment.
This will launch Outlook and attach.
Yes, awkward, but it does work. PLUS they have an entry in their send folder that it actually went.....
