Sent & Drafts will not download after re-configuring ATT account

Dell Inspiron Laptop, Windows 10.

Windows Live Mail stopped sending e-mails.

E-mail provider "AT&T" indicated the e-mail application was probably 'corrupted' and instructed to delete and re-install; no e-mails would be lost.

Deleted Windows Live Mail from my Dell Laptop, re-installed and re-configured.

All "Inbox" e-mails from the server were downloaded to the application. Great !

All "Sent" & "Drafts" will not download from the server to the Windows Live Mail application on my laptop, they are still on the AT&T server.

AT&T representative said it is a "Microsoft Application" problem and to contact Microsoft.

I'm in the endless loop of telephone tech rep. HELL !!

PLEASE HELP !! NEED TO RESTORE MY SENT BOX !!
