Emails you compose in Outlook are sent using the default account. (The default account setting also determines what appears in the From field and your signature file if you've created one.)

If you have multiple email addresses, you might have reason to send an email using a different account other than your default. Fortunately, Outlook makes it simple and quick to override the default email setting.

Instructions in this article apply to Outlook 2019, 2016, 2013, 2010; and Outlook for Office 365.

Choose the Account Used to Send a Message in Outlook

To specify the account from which to send a message in Outlook:

  1. In the compose message window, select From (to the right of the Send button).

  2. Select the desired account from the list. This is the account name that the recipient will see when they receive the email once you send it.

If you don't see the account you went to send from in the list, select Other Email Address from the dropdown. In the pop-up window you can search for another account to select as the send from account.

Change the Default Account

If you find you're using a different account more than the one you've set up as your default, you might want to change the default account to save time and keystrokes. Here's how:

  1. Select the File menu, select Account Settings and select Account Settings from the dropdown list.
