Is it possible to update tickets via e-mail in WHD?
Yes a user can just reply to the email and it will appear as new note on the ticket and will trigger emails to the tech. I have never tired emailing for a tech note but I would assume it would also work.
The big FYI on this one is do not change the subject line as that is how it parses the messages.
Have you been able to implement the email update feature yet in WHD? Any further questions?

Everything is working fine now But we noticed that even with hide notes from client checked if a Tech replies to the e-mail the Note is visible to everyone.
