Email Helpdesk

The best action is to set up a new folder, call it Old Emails and move everything in your Inbox to the Old Emails folder.  Use Ctrl-A to select everything in the Inbox and drag them with the mouse into the folder.

Then you allocate time, perhaps half an hour a day and preferably soon after you start work in the morning, to go through the list.  You will be surprised how quickly you can get through even a huge list if you concentrate for a set time. Be fairly ruthless in hitting the delete key - you can retrieve from the Deleted Items folder if you make a mistake. Don't continue beyond your allotted time or it will become a drudge.
