By default, Outlook does not automatically check for new e-mail messages. You can manually check for new e-mail messages as often as you want by clicking Send/Receive on the Standard toolbar.

You can set up Outlook to check for new e-mail messages at intervals of one minute to 1,440 minutes (one day).

1. On the Tools menu, point to Send/Receive, point to Send/Receive Settings, and then click Define Send/Receive Groups.
2. Select the group that contains the e-mail account that you want to regularly check for messages.

   Note  If you have not set up multiple send/receive groups, all of your e-mail accounts are contained in the All Accounts group.

3. Under Setting for group "group name", select the Schedule an automatic send/receive every x minutes check box.
4. Enter a number from 1 to 1440 in the minutes box.
5. Click Close.
6. On the Standard toolbar, click Send/Receive.

   Note  This is the only time you need to click the Send/Receive button.
