Hi. Using Posteo with Thunderbird, Windows 10. Twice now an email has simply vanished when all I did was left-click on the email in the left side pane email list, i.e. the Subject line heading. Each time it is an email sent to my Posteo email address, not anything synced. I did not click on Delete or anything else. I have searched every folder for the missing emails, they are nowhere to be found. They are not in the Deleted items folder or any other folder. This is a recent problem, in the last few weeks. I checked on my Posteo webmail, and there is no sign of the emails there either - so they have vanished from both. Inexplicably. Has anyone got any suggestions as to what is happening, why, and if there is a way of retrieving the emails? Thanks.
