Non-Gmail e-mail you fetch on your Samsung Galaxy tablet is typically left on the e-mail server. That’s because the Email app, unlike a computer’s e-mail program, doesn’t delete messages after it picks them up. The advantage is that you can retrieve the same messages later by using a computer. The disadvantage is that you end up retrieving mail you’ve already read and possibly replied to.
You can control whether the Email app removes messages after they’re picked up. Follow these steps:
Open the Email app.
Touch the Menu button and choose the Settings command.
On the left side of the screen, select a specific account.
Choose the More Settings command, and then choose the Incoming Settings command.
If you can’t find an Incoming Settings command, you’re dealing with a web-based e-mail account, in which case there's no need to worry about the manual delete option.
Below the Delete Email from Server item, select the When I Delete from Inbox option.
The only other option besides When I Delete from Inbox is Never. If you see the Never option, choose the other one.
Touch the Done button.
Repeat Steps 3 through 6 for any additional e-mail accounts you have.
After configuring the Delete Email from Server option, any message you delete in the Email app is deleted also from the mail server. It isn't picked up again, not by the tablet, another mobile device, or any computer that fetches e-mail from that same account.
Mail you retrieve using a computer’s mail program is deleted from the mail server after it’s picked up. That’s normal behavior. Your tablet cannot pick up mail from the server if your computer has already deleted it.
Deleting mail on the server isn't a problem for Gmail. No matter how you access your Gmail, from a mobile device or from a computer, the inbox lists the same messages.
