A number of Clients are having an intermittent issue whereby they cannot update a Ticket when replying via email. However, the next day, on the same Ticket, they can update no problem.
The different emails are exactly the same and using the Client is sending the email in the same way. The non-updating email just vanishes, doesn't appear in the Helpdesk Mailbox and the Client receives no error message.
Does anyone have the same issue?
