In our company we have many clients which are using Thunderbird to send and recieve there Emails. We create a new Newsgroup and smtp with the same settings for all. There is one Client with the issue of losing all configuration set. It happens one time per month. The newsgroup, smtp settings and so on are lost AND i don't know why. All the others don't have this issue. Do you guys have any ideas why this could happen? I am a little bit frustrated... Greetings from Robin
