Hello, I had this problem lately, the emails I had placed in a sub-folder have disappeared from one day to another, only those in this specific folded, I had them stored for months, and now they are all gone, folder empty. Of course I did not erased them nor gave any input to delete. If I wanted to delete them I would have it done one by one, not all of them but leaving the sub-folder. To me it is a serious problem, i store emails for any client and business, I cannot afford to lose them, anyone know what may have happened, and if I can get them back? No sign of them in Thrash either... thanks!
