Microsoft Outlook 2016 - Default Port - Setup Guide

Important Points

  • First you need to make sure the address(es) you will be sending from have been authorised on your account in our Control Panel
  • These instructions assume your email account has already been setup and is collecting email correctly.
  • Take a note of any settings you change
  • Only change the items specified - you should not need to change your incoming settings
  • These instructions are only for Microsoft Outlook 2016 - for other email programs please see How To Setup AuthSMTP
  • We have instructions for both default SMTP port and alternate SMTP port configurations - alternate port is generally used if your ISP blocks the normal port 25 SMTP access (as many do these days!)
