Using Outlook 2010 here and this seems to fix that issue. In the Control Panel, click on the "Mail" icon, then the "Email Accounts" button, then click once on your current email account in the "Email" tab to highlight it, then click on the "Change" heading button directly above it. At the next window, click on the "More Settings" button, then the "Advanced" tab, then UNCHECK the box next to "Leave a copy of messages on server". Click on OK, then the "Next" button to let Outlook send you a test message. Then the Finish button.
Hope this helps.

Hi,
My Windows 7 - Outlook 2010 for some reason has started downloading email as far back as 2016. It all started when I was having problems with my emails only downloading 1 day at a time, for example I had to hit the send/receive button each time to get emails from today, yesterday, the day before etc. The only thing I changed was under "Internet E-mail Settings" then "Advanced" I unticked "Remove from server after 100 days". Ive now changed it back but its still downloading duplicates". Can you help me to stop doing this and also help to delete duplicates please.
thank you kindly,
Cheers - HaloTop
