A customer have sent E-mails from VPE previews during many years using Thunderbird as mail client, but yesterday that stopped working for most of the clients on their network. When pressing the E-mail button, Thunderbird is open, but no mail is created. They just see their old mails.
They use Windows terminal server 2008 R2. A strange thing is that it works for one client, but not for the other. Any suggestions about how to attack this problem?
