Updated June 24, 2019

If you send a message from your Outlook Mail on the web, Outlook.com or Windows Live Hotmail account, but want to receive replies at another email address, you can change the Reply-to header by selecting a different email address that you've set up in Outlook.

Instructions in this article apply to Outlook.com and Outlook Online.

Receive Replies at a Different Address Sending From Outlook Mail on the Web

When you send an email in Outlook, Outlook Mail on the web uses the Reply-to address used in the From line. You can, however, change that address in the From line.

To pick a From address for an email you are sending from Outlook Mail on the web and receive replies at that address instead of your main Outlook Mail on the web email address:

Start a new message, reply, or forward.
Select the More commands icon (⋯) in the composition pane or window's top toolbar.
Select Show From.
Select From.
Choose the desired address.

Go to Mail > Sync email.

Add an email account in the Add a Connected Account section.
Select the Set default From address dropdown arrow and choose the address you wish to use.
