SMTP Configuration for Office 365 (MFA Enabled)

Click here if you do not have the option to create an App password

Use the following details if a broker uses Office 365 for their emails.

SMTP Server	SMTP Port	SMTP Encryption	SMTP Username	SMTP Password
smtp.office365.com	587	TLS	Your complete office 365 email	Your app password

Microsoft's enforcement of MFA and recent changes to their authentication methods have caused issues with SMTP authentication. The only solution we have at this time is to create an App Password in Office 365. Instructions on how to do this are below.

Note that the below instructions implement the same changes that are required if you were to have your printer/scanner send outgoing mail via Office 365.

To enable sending of your emails via Office365 at this point in time (Nov 2022) you must perform the following functions in your Office 365 tenancy configuration. This will likely require you to engage your IT support team.

1. Enable or disable authenticated client SMTP submission (SMTP AUTH) in Microsoft 365

The easiest way to do this is in the section titled 'Use the Microsoft 365 admin center to enable or disable SMTP AUTH on specific mailboxes'.

2. Disable Security defaults in Microsoft 365

Having Security Defaults enabled imposes a number of security rules which includes disabling any basic authentication. Basic authentication has to be enabled in order for SMTP sending to work.

3. Create an App Password

The current version of the portal interface is slightly different to that described in the linked Microsoft documentation.

In your Microsoft 365 portal, go to My Account and click on Security Info. The 'Add sign-in method' and select the App Password method.
