Outlook 2013 introduced the ability to send an email from an email address that is not defined as an Outlook account. This article describes how to send an email from other email address in Outlook 2013 – 2019.
Until Outlook 2013, unless you were using Outlook as a client for a Microsoft Exchange server, you couldn’t send an email from a non-Outlook email account. If Outlook was connected to Exchange, you could use the “Send on Behalf of” feature that allows you to put a different email address in the email “From:” field. Microsoft changed it with Outlook 2013.
Send from other email address – Outlook 2013 – 2019
With Outlook, you can specify ANY email address in the email “From:” field. To send from other email address, simply create a new email and click on the “From” field, then choose “Other E-mail Address”:
An Outlook popup window will be displayed. On this window, you can type ANY email address that shall be used as the “From:” field. You can send an email from Bill.Gates@microsoft.com, if you want to! Since that email address is not defined in your Outlook profile and so Outlook doesn’t know its mail server, you also have to select the actual Outlook account through which you want to send the email:
Issues sending from other email address
Please note that:
– such emails sent from other email addresses have a higher probability to be marked as spam emails (because they are not sent through an authenticated connection of the “From” email address);
– if the person receiving the email replies to it, the reply is going to be sent to the other email addresses that was specified in Outlook. So make sure you actually have access to this email address, otherwise you will not get to see the email replies;
– the person receiving the email can see that the email was sent through a different email account. As you can see below, Gmail shows that the email was sent through a different domain:
As a final comment, don’t think about using the “Send from other email address” feature as a tool to send spam! Obviously, you shouldn’t think to send spam emails anyway, but this Outlook feature actually uses the SMTP email server of your Outlook account, meaning that – if your email is marked as spam – it can be tracked back to your actual email account / SMTP server.
