How to empty a folder in WebMail
– You can empty folders in webmail easily. To empty a folder, first click ‘Settings’.
– From the far left menu, select ‘Folders’, select the folder you wish to empty by clicking on the name of the folder (ignore the tick to the right, that refers instead to your subscription to this folder and not to whether or not you have selected it to be emptied), commence to click the cog icon at the bottom of the column and select ‘Empty’.
