Thanks everyone for sharing all this. I made this change. It stopped the duplicates from being created in my GMAIL sent items but now Outlook does not save them in sent items, forcing me to go to the internet and log into gmail to see my sent mail. I use Outlook exclusively as my email interface and GMAIL solely as the server. This started happening when i got a new computer and reconfigured my email. I'm not sure if I inadvertently changed my configuration somehow or if Google or Microsoft changed the way this all works. I used Outlook with GMAIL for years and never had this problem and was able to have a single copy of sent mail in Outlook and in GMAIL. Frustrating.
