How to Send an Email with a Different From Address in Outlook
Firstly, you will need to open a New Email. In the compose window, navigate to Options in the top banner.
Click on the From button. The From option will now appear above the To field.
Select From and choose which email address you want to use. If the email address is not showing select Other Email Address. Type the email in and then click OK, the email should now be showing in the From field.
The email addresses you choose will be saved so the next time you want to send an email using that account you can quickly select it using the arrow next to the From button.
