How does this change affect you?
The changes will be made at an environment level, therefore there will be no impact to you other than the outage window.
Third party programs and applications:
If you use a program or application to access your email, e.g. Outlook or MAC Mail etc. you will need to ensure that for the settings of the Outgoing Mail Server ‘SMTP Authentication‘ is now ticked (or enabled) and your email address and password is entered into the authentication details.
You will be required to make this change to the settings of your third party program in order for you to be able to authenticate with the server and be able to send and receive email. Instructions on how to do this with the most well-known programs and applications can be found here.
Enabling “SMTP Authentication” was not a requirement previously for your email to work, therefore it is important that you check this setting.
