I've been using TB for years, with several filters for incoming mails. In August 2020 I noticed that 2 filters were not working properly. One filter was moving the mails to the wrong folder, which continues after deleting the filter and setting the same as a new filter More annoying, one filter did the mails filtered disappear. In the settings of this filter, it was set to moving the mail but no folder was defined, although for years it was functionning properly to a specific folder, that still exists. I lost confidence in the filtering engine and had them desactivated. Does anyone know where I can find the lost mails : they are not among the deleted mails, neither junk, neither archives I should add that this is an exchange account, that I use with the Chouette add on Thank you in advance for your answers
