I have Microsoft Outlook 2007. My emails have stopped coming in, although showing progressing. Recently, my older years of emails began coming in. I researched and found to to Account Settings, Advance and uncheck the box to leave a copy on the server.
Apologies, but I'm not sure of the problem you're having. You state that your emails have stopped coming in and then you said that you found account settings. Did you make a change? Are you still unable to receive emails? Please check your webmail access to your account. If you're seeing email normally (send and receive), then your email is working and the issue as at your email client. You should leave a copy on the server - this will keep you from losing emails should they get lost on your local computer. You can also go through this article How to Troubleshoot Receiving Email to help resolve the problem.
