Microsoft Outlook makes it easy to always use plain text when emailing a contact who prefers plain text email over rich or HTML formatting. Simply set that preference in your address book, and Outlook automatically converts messages to that address to plain text no matter what format you use to compose the message.

Instructions in this article apply to Outlook for Microsoft 365 and Outlook 2019, 2016, 2013, 2010, and 2007.

To make sure Outlook always sends emails in plain text to certain addresses:

  1. Go to Outlook's navigation pane and select ​People or Contacts (depending on the version of Outlook you use), or press ​Ctrl+3. In Outlook 2007, select Go > Contacts.

  3. Locate and double-click the desired contact.

  4. Select the Email dropdown arrow and choose the email address you want to set to plain text.

  5. In the upper-right corner, double-click the email address that should receive plain text messages.
