Send and receive messages
This guide xplains the how messages are sent and received to your Outlook.
The standard way to manually send the messages in your Outbox and check for new incoming mail is achieved by clicking the send/receive button on the standard toolbar. In most cases, e-mail messages are sent automatically whenever you click Send in the new message window, and received at several possible times, including when starting Microsoft Outlook, at automatic intervals, and upon manual Send/Receive requests.
To Send and receive messages for all accounts on the Tools menu, click Send/Receive >Send/Receive All.

To Send and receive messages for a selected account on the Tools menu, click Send/Receive> account. Click Inbox.

Note: By default, messages are sent by using the account specified as the default in the E-mail Accounts Wizard. When you open a new message in Outlook, you might find that the Send button on the toolbar is missing. For the Send button to be available, you must have an e-mail account set up in your Outlook profile.
