Following these instructions will allow you to send messages through Pobox's SMTP servers, with your From address being your @pobox.com address, or your personal domain address, if you set one up for your account.
To begin, click on File in the top left hand corner of the page:
On the following page, click on Add Account:
On the next window, input your @pobox.com email address, click "Advanced options" and check the box next to "Let me set up my account manually".
Next, you will be able to select the mail account you wish to configure. Select "IMAP".
After you select the mail account you want to configure, you will be prompted to input the incoming and outgoing mail server information.
For the incoming mail server input:
Server: mail.pobox.com
Port: 993
Encryption: SSL/TLS
Outgoing mail:
Server: smtp.pobox.com
Port: 587
Encryption method: STARTTLS
When completed, click on "Connect".
Once you click "Connect" a new window will pop up that will ask for your incoming mail server password.
The password you should enter is your Pobox account password or your application specific password if you have two-step verification enabled.
Check the box next to "Save this password in your password list" and click OK
After you click OK, you will be required to input your password again for the outgoing mail server.
The password you should enter is your Pobox account password or your application specific password if you have two-step verification enabled.
Check the box next to "Save this password in your password list" and click OK.
Once you click OK you will be redirected to your Outlook inbox where you should now see your Pobox inbox in the menu on the left the Outlook window.
To confirm that your account is configured properly, click the "Send/Receive All Folders" in the top left of your Outlook window or press F9. You will see a window pop up and start to run a test to make sure you're able to send and receive mail with your newly configured mail account.
Your Outlook 2016 client should now be configured with your Pobox account.
