I have gmail setup on my HTC Eris. I have used Outlook Express for years. I have Outlook Express set to leave a copy of the message on the gmail server. Outlook Express on my desktop uses pop to get messages and leaves a copy on gmail. My Droid's gmail account will get a message but when Outlook gets new mail from the server the email disapears out of the droid's gmail list. My Droid will say "No Conversations". What setting do I have to use on the Droid or in Outlook so the email doesn't get removed from my Droid gmail account?
