Hello, I reply all to sent messages so that the details of the previous email are on my mail and my additions to it (new email) are on top, with the same addressees so they don't have to be added again/aren't missed. This has worked for years with the sent message going in SENT I recently updated Thunderbird and now the sent messages have disappeared. Is this a me/user error or has something changed? And how can I make sure it works like it used to? Best wishes Tim
