Email communication plays an important role in daily accounting tasks, and Sage 50 allows users to send invoices, purchase orders, customer statements, and financial reports directly from the application. While many businesses use Microsoft Outlook for email integration, others prefer SMTP (Simple Mail Transfer Protocol) because it provides a direct and reliable way to send emails without relying on an Outlook profile.
Configuring SMTP correctly in Sage 50 ensures that emails are delivered securely and efficiently. However, incorrect server details, authentication errors, firewall restrictions, or outdated settings can prevent emails from being sent successfully.
This guide explains Sage 50 SMTP settings, how to configure them, common SMTP errors, and the steps you can take to resolve email delivery issues.

What Are SMTP Settings?
SMTP stands for Simple Mail Transfer Protocol, the standard method used to send emails across the internet.
Instead of depending on Microsoft Outlook, SMTP allows Sage 50 to communicate directly with your email provider's outgoing mail server.
When configured correctly, SMTP enables you to:
Send customer invoices
Email purchase orders
Deliver customer statements
Send quotations
Share financial reports
Communicate directly from Sage 50
Businesses that use Gmail, Microsoft 365, Exchange Online, or custom mail servers commonly rely on SMTP for email delivery.
Why Use SMTP Instead of Outlook?
Although Outlook integration works well for many businesses, SMTP offers several advantages.
No Dependency on Outlook
SMTP sends emails directly through your mail server without requiring Microsoft Outlook to be installed or running.
Better for Multi-User Environments
Businesses with multiple accounting users often find SMTP easier to manage because every workstation can use the same mail server settings.
Improved Reliability
SMTP reduces problems caused by Outlook updates, damaged mail profiles, or Office compatibility issues.
Compatible with Many Email Providers
SMTP works with:
Microsoft 365
Gmail
Exchange Server
Business email hosting providers
Custom corporate email servers
Information You'll Need Before Configuring SMTP
Before opening Sage 50, gather the following details from your email provider.
SMTP Server Address
Examples include:
Your company's mail server
Always use the server recommended by your email provider.
SMTP Port Number
The most common ports are:
Port | Purpose |
25 | Legacy SMTP (rarely recommended) |
465 | SSL encryption |
587 | TLS encryption (most common) |
Most providers recommend Port 587 with TLS.
Email Username
Usually this is your complete email address.
Example:
Email Password
Enter the password associated with your email account.
If your provider uses multi-factor authentication (MFA), you may need an app-specific password instead of your normal login password.
Encryption Type
Most providers require one of the following:
SSL
TLS
Selecting the wrong encryption method is a common cause of SMTP connection failures.
Preparing Sage 50 for SMTP Configuration
Before entering your SMTP settings:
Install the latest Sage 50 updates.
Confirm your internet connection is working.
Verify your email credentials.
Disable "Work Offline" mode if applicable.
Ensure your firewall allows outbound SMTP connections.
Back up your Sage 50 company file.
These simple checks can prevent many setup issues later.
How to Configure SMTP Settings in Sage 50
Follow these steps to configure SMTP correctly.
Step 1: Open Sage 50
Sign in using an account with administrative privileges.
Step 2: Open Email Preferences
Navigate to your company's email settings or preferences section.
Depending on your Sage 50 version, the location may vary slightly.
Step 3: Choose SMTP as the Email Method
If Outlook is currently selected, change the email method to SMTP.
Step 4: Enter SMTP Server Information
Provide the following details:
SMTP server name
Port number
Username
Password
Encryption type
Double-check every field before saving.
Step 5: Enable SMTP Authentication
Most email providers require authentication.
Enable the authentication option and enter your username and password.
Without authentication, many mail servers reject outgoing emails.
Step 6: Save the Configuration
Save your settings and close the email preferences window.
Restart Sage 50 to ensure the new settings are applied.
Step 7: Send a Test Email
Before sending invoices to customers, perform a test.
Create a sample document and email it to yourself.
Verify that:
The email is delivered.
The attachment opens correctly.
No SMTP errors appear.
The email arrives within a reasonable time.
A successful test confirms that your SMTP configuration is working.
Understanding Common SMTP Ports
Choosing the correct port is essential for successful email delivery.
Port 587
This is the recommended option for most modern email providers.
It supports TLS encryption and is widely accepted for secure email transmission.
Port 465
Some providers still support Port 465 using SSL encryption.
If your provider recommends SSL, use this port.
Port 25
Port 25 is primarily used for server-to-server communication and is often blocked by internet service providers.
Avoid using this port unless specifically instructed by your email administrator.
Tips for Successful SMTP Configuration
To improve email reliability:
Use the SMTP settings provided by your email provider.
Verify your username and password carefully.
Keep Sage 50 updated.
Test your configuration after Windows or network changes.
Use secure encryption (TLS or SSL).
Review SMTP settings whenever your email password changes.
Following these recommendations can help prevent common SMTP issues.

Gmail SMTP Settings for Sage 50
Many small businesses use Gmail for sending invoices and financial documents from Sage 50. Before configuring Gmail SMTP, ensure that your Google account allows SMTP access.
Typical Gmail SMTP Settings
Setting | Value |
SMTP Server | |
Port | 587 (TLS) or 465 (SSL) |
Authentication | Required |
Username | Your full Gmail address |
Password | App Password (recommended if using 2-Step Verification) |
Encryption | TLS or SSL |
Note: If your Google account uses 2-Step Verification, you'll typically need to generate an App Password for Sage 50 instead of using your normal Google password.
After entering these settings, send a test email to verify the connection.
Microsoft 365 SMTP Settings
Organizations using Microsoft 365 can configure Sage 50 to send emails through Microsoft's SMTP service.
Typical Microsoft 365 SMTP Settings
Setting | Value |
SMTP Server | |
Port | 587 |
Authentication | Required |
Encryption | TLS |
Username | Your Microsoft 365 email address |
Password | Your Microsoft 365 password or organization-approved authentication method |
If authentication fails, verify your account credentials and check with your Microsoft 365 administrator to ensure SMTP authentication is permitted.
Using a Custom Business Email Server
Many companies use email hosting from providers other than Google or Microsoft.
Before configuring Sage 50, collect the following information from your IT department or email hosting provider:
SMTP server address
SMTP port number
Encryption type
Authentication requirements
Username
Password
Using incorrect server information is one of the most common reasons emails fail to send.
