Setting up Office365 SMTP For ScanEZ

If you’ve just created a new Office 365 account and are having trouble using it for scan to email (SMTP), you’re not alone. This is common with new accounts because a default setting blocks SMTP authentication. Don’t worry—this guide explains why this happens and how to fix it so your scanner or multifunction device can send emails as intended.

Why Your New Office 365 Account Can’t Send Scan to Email

When you set up a new Office 365 account, Microsoft sets the SmtpClientAuthenticationDisabled property to TRUE by default. This setting blocks devices and apps from authenticating with SMTP, which scan-to-email functionality requires. To enable scan to email, you’ll need to change this setting to FALSE.

How to Enable SMTP Authentication for Your New Account

You’ll need to use the Microsoft 365 admin center or Exchange Online PowerShell to change this setting. Below are the step-by-step instructions using PowerShell, which is the quickest way to update this property.

Step 1: Connect to Exchange Online PowerShell

1. Open PowerShell on your computer.

2. Install the Exchange Online module if you haven’t done so already. Run:
   Install-Module -Name ExchangeOnlineManagement

3. Connect to Exchange Online:
   Connect-ExchangeOnline -UserPrincipalName youradmin@yourdomain.com
   Replace youradmin@yourdomain.com with your admin account.

Step 2: Enable SMTP Authentication for the Account

1. Identify the user account that your scanner or device uses to send emails.

2. Set SmtpClientAuthenticationDisabled to FALSE by running:
   Set-CASMailbox -Identity user@yourdomain.com -SmtpClientAuthenticationDisabled $false
   Replace user@yourdomain.com with the correct email address.

Step 3: Confirm the Change

1. To verify that SMTP authentication is now enabled, run:
   Get-CASMailbox -Identity user@yourdomain.com | Select SmtpClientAuthenticationDisabled

2. The result should be False.

Additional Tips for Scan to Email Setup

• Check device settings: Make sure your scanner or multifunction device is configured to use smtp.office365.com, port 587, and STARTTLS encryption.

• Password issues: If your account uses Multi-Factor Authentication (MFA), you’ll need to generate and use an app password for your device.

• Licensing: The account you use must be licensed for Exchange Online.

• Firewall settings: Ensure that outbound connections to smtp.office365.com on port 587 are allowed on your network.
