Office 365 mail port

In Office 365, the mail port is also known as the Simple Mail Transfer Protocol (SMTP) relay. It's a secure way to send and receive emails from your Office 365 account. Here's how to find and use your Office 365 mail port:

Finding your Office 365 mail port:

1. Sign in to the Office 365 admin center: https://admin.microsoft.com
2. Click on "Settings" (gear icon) in the top right corner, then select "Organization" > "Mail" > "Mail settings"
3. Scroll down to the "Outbound connections" section and click on "Edit"
4. Look for the "SMTP relay" section and note down the "SMTP relay server" and "SMTP relay port" values

Using your Office 365 mail port:

To send emails from your Office 365 account using the mail port, you'll need to configure your email client or application to use the following settings:

• SMTP Server: The SMTP relay server value you noted down earlier (e.g., smtp.office365.com)
• SMTP Port: The SMTP relay port value you noted down earlier (e.g., 587)
• Username: Your Office 365 email address (e.g., your_email_address@your_domain.com)
• Password: Your Office 365 password
• Authentication: Use the "Username and password" option

Here are some examples of how to configure popular email clients:

• Outlook: Go to File > Account Settings > Account > More Settings > Outgoing Server > Use same settings as my incoming mail server
• Gmail: Go to Settings > Accounts and Import > Send mail as > SMTP server: smtp.office365.com, Port: 587, Username: your_email_address@your_domain.com, Password: your_password
• Thunderbird: Go to Account Settings > Outgoing Server > Edit > Server: smtp.office365.com, Port: 587, Username: your_email_address@your_domain.com, Password: your_password

Remember to replace your_email_address@your_domain.com and your_password with your actual Office 365 email address and password.

If you're having trouble connecting to your Office 365 mail port, you can try the following troubleshooting steps:

• Check your Office 365 account settings to ensure that your email address and password are correct.
• Verify that your email client or application is configured to use the correct SMTP server and port.
• Check for any firewall or antivirus software restrictions that might be blocking the connection.
• Contact your Office 365 administrator or Microsoft support for further assistance.
