Good morning , For some time now, e-mail messages have been disappearing from my inbox. (I found out when I tried to find the message in the history) I checked with the supplier home.pl and according to their technicians there is no problem on their side. According to home.pl, the problem lies with Thunderbird and probably with the program's internal settings. It is possible that emails are archived to a file every 30 days (home.pl opinion) However, I don't remember setting up Thunderbird this way. Please help me how to recover or possibly find a file containing e-mails that disappeared only from my inbox. Messages in the sent folder are retained.
