If you often change the From line in Outlook.com one email at a time, consider setting up a default From address to save time. In this way, all new emails automatically will be sent through the connected account you select, and its address will display in the From field.

Instructions in this article apply to Outlook on the web and Outlook for Microsoft 365.

To designate the email address to be used by default in the From field in messages you compose using Outlook.com:

  1. Select Settings (the gear icon in the top navigation bar).
