HOW TO SETUP OUTLOOK TO SEND EMAIL USING A FORWARDING ADDRESS

If you have setup a forwarding address in cPanel (i.e. an email address that forwards all emails to an email account), you can still set it up in Microsoft Outlook (express) so that when you reply to an email sent to that address, the 'reply-to' address that the recipient sees will be the same email as the forwarding address.

Here's how:

You need to set up a fake alternative account in Outlook.

1) Click on 'Tools'

2) Click on 'Accounts'

3) Click 'add'... then 'mail'...

4) Type in your email forwarding address e.g. yourname@yourdomain.com

5) Put a dash ('-') for 'incoming mail'

6) Type in smtp.yourdomain.com

7) Click next (it will tell you that you don't have a valid inbox, but click 'yes', you want to use it.

8) Type in a dash ('-') for your account name and ('-') for your password.

9) Click finish - You have just setup a fake email account (it's fake because it's just a forwarder account, and does not need a valid inbox address because there is no valid email account to check (as all email is forwarded to your inbox account)). 

10) You now want to stop Microsoft Outlook from 'checking' the forwarding email address (because no inbox exists).

Click once on the account name you just set up, and click 'properties'.

11) Untick 'include this account when receiving or synchronizing'

12) Click 'ok', then click 'close'.

Now, whenever you reply to an email that someone has to sent to a forwarding address, that forwarding address will appear in their 'reply to' box.

You should also note that when you are sending a new email, a 'From' dropdown box will appear, where you can select what email address you want the email to appear to be sent from.
