In New Outlook for Windows, select New > Mail or press Ctrl+N to compose a message, then select Send. To check for new mail, select Mail > View > Sync or press F9; the classic Outlook Send/Receive tab is not used in New Outlook.

If messages are not moving, check your connection and sync status, verify the sending account, and consider Microsoft cloud storage, attachment size limits, or provider sign-in requirements.

Send an email in New Outlook

  1. Select New > Mail on the ribbon, or press Ctrl+N.
  2. Enter recipients in To, Cc, or Bcc. To show Bcc if it is hidden, select Options > Show Fields > Bcc.
  3. Enter a subject and write your message.
  4. To attach a file, select Insert > Attach File. To attach an Outlook item, such as a message, contact, task, or calendar item, select Insert > Outlook Item.
  5. If you have more than one account, check From and select the account you want to send from. If From is hidden, select Options > Show From.
  6. Select Send.

The Send button may not appear until an email account is configured. New Outlook supports Microsoft accounts such as Outlook.com and Hotmail, organizational work or school accounts, and third-party accounts including Gmail, Yahoo, and iCloud. Third-party accounts can connect through IMAP.

Choose the From account

For a new message, Outlook uses the default account unless you choose another account in From. Replies and forwards use the account that received the original message. If you have only one email account in your profile, From may not be shown.

Fix common sending and receiving problems

  1. Check your internet connection. Confirm the computer is online, then run View > Sync and watch for the sync status message.
  2. Verify the sender. When composing a new message with multiple accounts, check that From shows the intended account.
  3. Check Microsoft cloud storage. Microsoft says full cloud storage can prevent sending or receiving email.
  4. Consider attachment size. An attachment may exceed the recipient provider’s limit. A large message can block that message and messages queued after it, so try reducing or removing the attachment.
  5. Follow third-party sign-in guidance. If Outlook requests an app password or another authentication step, follow the email provider’s instructions. Requirements vary by provider.

Shared mailbox synchronization

In New Outlook, incoming messages in the Inbox of a shared mailbox added through automapping do not automatically synchronize. Select View > Sync or select the shared-mailbox folder to update it. Microsoft suggests adding the shared mailbox as an account if automatic synchronization and notifications are needed.
