Microsoft Exchange 2019 - SMTP Connector - Setup Guide

Important Points

• First you need to make sure the address(es) you will be sending from have been authorised for your account in our Control Panel .

• You cannot configure your Exchange server to automatically forward email to a remote email address using your AuthSMTP account, for more information please see - Can I use AuthSMTP to automatically forward email?

• These instructions assume your Microsoft Windows server has already been setup, you have installed Microsoft Exchange Server 2019 and your incoming email is setup and working.

• The guide will walk you through creating a new SMTP Connector for general use, any further configuration to limit use of this connector to specific parts of your network or users is your responsibility, Microsoft can provide you with support for Exchange 2019 via their website - Exchange 2019 General Documentation.

• The common errors that can happen when trying to configure our service will be logged to your account history in the Control panel -> Account Usage -> Error Log with the exception of incorrect username / password errors, so if you are having a problem please check those error logs.
