I have the same problem but not as bad as you do. I have Windows 7 and use Windows Live 2012 and have it set up with IMAP. When I send e-mail it saves it in a folder called "Sent Items". On the left side
I have Charter (thetaz00) with folders called Inbox, Drafts, Sent Items,
Sentmail (no space between words), Junk E-mail, Junk Mail, Deleted Items and
Trash. Right below that I have Outbox with no folders. Below that I have Storage folders with folders Drafts, Sent items and Deleted items. Don't know why they would have two different sent folders and two different junk folders with different names. To me
if I'm sending mail it should go in a folder called Sent Mail.
I just keep playing around and finally figured out how to get sent mail to go to the folder I want it to go in which is Sent Mail. I'll try and do my best to talk you through it. I have Windows 7 but it is still Windows Live Mail 2012. Of course go to Windows
Live Mail. Then under home to the left side you should see your carrier and your default account. Mine says Charter and (thetaz00). Right click that and go to the popup at the bottom and click properties. You will get another popup with General, Servers, Security,
Advanced and IMAP. Click on IMAP and you should see Folders and Special Folders. Under Special Folders you will see Store special folders on IMAP server. Under mine I see
Sent Items path: Sent Items
Drafts path: Drafts
Deleted Items path: Deleted Items
Junk path: Junk E-mail
Next to Sent Items path: it says Sent Items. I just changed Sent Items to Sent Mail (with a space). I clicked apply and OK. You will get another popup that says "You have made some changes that may affect your list of folders. Would you like to refresh your
folder list? Click Yes. I then created a new e-mail and sent it to myself. Under subject I just put Test and in the header Test again. I then hit send. In a few seconds I received the e-mail in my Inbox. Now this took a little longer about a minute but I checked
my Sent Mail folder and a copy of the E-mail was in there and not in my Sent Items folder. Under my IMAP properties I only have these 4 folders showing with the new location Sent Mail which I changed from Sent
Items.
Sent Items path: Sent Mail
Drafts path: Drafts
Deleted Items path: Deleted Items
Junk path: Junk E-mail
and where the information should go. You can go back to the left side and delete and folders you don't want especially the duplicate folders. The only ones you cannot delete are the ones you have assigned under your IMAP properties. Two other folders you
cannot delete are your your Inbox folder or your Trash folder. I just deleted the extra Sent folder and the extra Junk folder. Now it looks clean with only six folders that you only need.
Inbox
Drafts
Sent Mail
Junk E-mail
Deleted Items
Trash
I hope I didn't make it to confusing for you. Good luck in cleaning up all those extra unneeded folders. If you run into any problems just reply back and I'll see if I can help you. GOD BLESS AND HAVE A NICE DAY.
