Cannot uncheck the box selecting email then change your mind without uncheck all boxes.
In my deleted email window I checked a few boxes to label them spam but wanted to change my mind for one of them. I am not allowed to uncheck one box out of many without unchecking all of them. This is the same in the inbox too. With gmail I can check the all box and go down and uncheck boxes I don't wish to delete. This is very helpful if you choose not to read 25 or so emails out of 30. You are able to uncheck each box seperately. Not so with ATT/Yahoo mail.
