Software & Apps MS Office How to Choose the Account Used to Send a Message in Outlook If you have multiple accounts, change what appears in the From field by Heinz Tschabitscher Writer A former freelance contributor who has reviewed hundreds of email programs and services since 1997. our editorial process Heinz Tschabitscher Updated on March 09, 2020 MS Office Outlook Word Excel Powerpoint Tweet Share Email When you send an email message using Microsoft Outlook, Outlook chooses your default account as the From account. But if you have multiple Outlook email accounts, it's easy to change what email address appears in the From field. Instructions in this article apply to Outlook 2019, 2016, and 2013, as well as Outlook for Microsoft 365. Choose the Account Used to Send a Message You may have various Outlook email accounts for different purposes, for example, a business account, a school account, and an account for a volunteer organization. To specify the account from which you're sending the message: In the New Message window, select From. Select the desired account from the list. This is the account name the recipient will see when they receive the email. If you see the Send button, but not the From button, it means your Outlook profile contains only one email account. To view the From button, you'll need to add another email account. Change the Default Account If you use a different account more than the one you set up as the Outlook default account, change the default account to save time and keystrokes. Go to the File tab and select Info. Select Account Settings > Account Settings. Choose the account you want to use as the default send account, then select Set as Default. Select Close to save your changes and close the window.
