What Happens When 'Send immediately when connected' Is Enabled?

When the Send immediately when connected option is enabled in Outlook and you click Send, what happens next depends on whether you are connected to a network and whether Outlook is offline or online:

  • If you are connected and Outlook is set to Work Online, the message is delivered immediately unless Outlook runs into an error. In that case, it attempts delivery periodically thereafter.

  • ​If you are connected and Outlook is set to Work Offline, ​Outlook will not deliver the email. The message is kept in Outbox until you set Outlook to Work Online.

    Outlook attempts to send the message while offline if the account is part of a Send/Receive Group that is set to attempt mail delivery according to a schedule while working offline.

  • If you are not connected and Outlook is set to Work Online, ​Outlook sends the email but returns an error. The message is kept in Outbox. Outlook attempts to deliver the email a few minutes after you have connected.

  • If you are not connected and Outlook is set to Work Offline, Outlook will not deliver the message immediately.
