First you need to make sure the addresses 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
Make a note of any settings that you change
Only change the items specified - you should not need to change your email address or POP3 / IMAP settings
These instructions are only for Outlook for Apple Mac OS X (v16.x) - for other programs see How To Setup AuthSMTP
Open the Microsoft Outlook app on your Apple Mac computer
Once open, click on the 'Tools' menu from the navigation at the top of your screen
Click on 'Accounts'
You will now see a list of accounts setup in Outlook for Mac
Click on the account you wish to setup with AuthSMTP in the left-hand column
You will then see the current settings for this account, please make a note of these before making any changes
The next step is to determine if you are using Microsoft Cloud Sync, if the text is visible as shown in the image below that does mean that it is enabled.
If you are not using Microsoft Sync, please proceed to Step Five
If you are Microsoft Sync, you will not be able to modify the SMTP server settings as they have synchronised to your other devices
The only way this can be disabled is by removing the email account from Outlook entirely and re-adding it with Microsoft Sync disabled. This is not something we can guide you through or recommend that you do unless you are confident in doing so and understand the implications, if in doubt please consult with an IT professional.
You can now change the settings to use your AuthSMTP account
