Configuring Multiple Send From Addresses / Outlook Email Accounts

It’s simple to send (and receive) email from multiple addresses within Outlook.

You may use alternate email addresses established within your Exchange or ISP mail account,  (e.g., or secondary personal or shared email accounts (e.g. These must be valid, operational email addresses with passwords.

The first step is get the email address set-up with your Exchange admin or ISP.  Then you just need to set-up an additional account within Outlook.]

  1. Use the Outlook menu, File > Work Offline, now close and reopen Outlook
  2. Open Outlook, and go to Tools > Account Settings

  3. In Account Settings, on the Email tab, click New

  4. If you are using an additional email address within your primary account, then select the option which includes POP (Post Office Protocol) email service (SMTP)—which must be enabled by your Exchange Admin first.

    If this is a separate email account with a separate inbox, use an Exchange account.

  5. Check the box to Manually configure server settings and click Next.

  6. Fill in your details.  For Account type: use POP3 or Exchange as discussed in step 4. For the incoming and outgoing server names, use the server names provided by your ISP or Exchange Admin (or copy them from your existing active account, if coming off the same server(s)). Leave the box for Require logon using Secure Password Authentication unchecked.

  7. Click the More settings button
  8. In the Outgoing Server tab, check the box for My outgoing server (SMTP) requires authentication

  9. In the Advanced tab, use the following settings:
    Incoming server (POP3): 995Check the box for This server requires an encrypted connection (SSL)
    Outgoing server (SMTP): 25  (or the port number specified by your ISP or Exchange Admin)
    Use the following type of encrypted connection: TLS
    In the Delivery section, check the box for Leave a copy of messages on the server
    Click OK to close the Internet E-mail Settings dialog

  10. Click the Test Account Settings button. If Outlook is not able to log on and send a test message, review the error message and adjust the settings accordingly, or see your email Administrator.
  11. Close the Account Settings dialog.
  12. From Outlook’s Inbox, click Send/Receive down arrow button on the toolbar, to access the Send/Receive menu:  Send/Receive > Send/Receive Settings > Define Send/Receive Groups

  13. If you are not adding a new account with a separate inbox, then within the Account section, click on the icon to select the email address you added, then uncheck the box for Receive mail items (this will prevent duplicate mail items from loading into your one Inbox, one for each address you have added).

  14. Use the Outlook menu, File > Work Offline (to go back online), then click the Send/Receive button.
  15. You are done. Now whenever you start a New Outlook message, you may use the Account button (found under the Send button) to select your alternate Send From address.
  16. Note: If you send yourself a test message from the alternate account, and use Exchange Server, the email may still appear to come from your primary account (because Exchange may resolve both addresses to your primary address – you are you). To ensure the Send From is working the way you want, send to another user and send to an outside email address, such as your Hotmail or Gmail address.
