Here are a few tips to help you keep your mailbox uncluttered.

1. Make sure your Trash is empty. If it isn't, click the Empty Trash button on the Mailboxes screen.
2. From the Mailboxes list, identify any mailboxes that have the biggest size. Look through those for unwanted messages. Be sure to check your Sent box from time to time.
3. In your INBOX (or any other mailbox), sort by size to see which messages are the biggest:
   • Open your INBOX
   • Click on the word "Size" at the top of the columns that gives the message sizes. The first time you click, it will sort with the smallest ones first.
   • Click on the heading "Size" again to sort with the largest ones first.
   • Delete messages as you see fit.
   • To sort back to the usual order, click on the header "Received". If you get the oldest ones listed first, click on "Received" again.
4. Delete "duplicate" messages. Once you have sorted by size, you will often see two or more messages with nearly the same size where you have perhaps received a message with an attachment and then replied or forwarded it on. You should be able to delete all but one of those.
5. File attachments to your local hard drive. If you have a large e-mail message, it almost certainly contains an attachment.
   • Open the message
   • Scroll down to the bottom to see the attachment(s)
   • Right-click on the attachment icon and select "Save Target As"
   • Save it to the location you choose. I have a folder called "Attachments" that I use specifically for this purpose.
   • Once the attachment is saved - if you don't need the contents of the message itself - delete the message.
