Send and receive messages in Outlook for Windows

Outlook 365
By default, Outlook automatically checks for new incoming and outgoing messages when it starts and at certain intervals defined in the Send and Receive groups. In addition, if your computer is connected to a network, e-mail is automatically sent by default when you click the Send button:

You can change the intervals between sending and receiving e-mail at any time and cancel sending and receiving messages immediately.

Send a message

After clicking the Send button, Outlook moves the message to the Outbox folder:

  • Attention! Because messages are not sent immediately, it is not recommended to turn off or close Outlook immediately after clicking the Send button. Many miscommunication problems are caused by the sender being convinced that the message has been sent and immediately turning off the computer or closing the laptop after pressing the Send button. In fact, the system needs some extra time to send messages.

    Therefore, before you close Outlook, turn off the computer or laptop and ensure no unsent messages are in your Outbox folder.

The message will be sent only in the Send/Receive session if there are no unexpected errors. Automatically, Outlook moves sent messages from the Outbox folder to the Sent folder (used by default if there are no other settings for outgoing messages - see more about saving copies of messages in the Sent Items folder).

Note: If Outlook is configured to send messages immediately after you click the Send button, you won't be able to change anything about your message before it's routed to the recipients (unless you're using Exchange Server).
