Description of the issue

Just upgraded to FM 14 server and all workstations to FM 14pro. final conversions went well and most things seem to working great. Most except for emailing. All previous email scripts fail. ( error -1 ) I've tried sending via email client as well as smtp server, same error. I've tried sending via the send mail under the file drop down menu and same thing. Am I missing a setting somewhere? setting in server? I've re-written a simple email script and same there as well.
Previously all files were hosted on FM server 11.
