Office 365 outgoing mail server settings

Here are the outgoing mail server settings for Office 365:

Outgoing Mail Server (SMTP)

• Server name: smtp.office365.com
• Port: 587 (or 25, but 587 is recommended)
• Authentication: TLS (Transport Layer Security) or STARTTLS
• Username: Your Office 365 email address (e.g., [email protected])
• Password: Your Office 365 email password

Notes:

• Make sure to use the correct server name and port number. Using the wrong server name or port number may cause issues with sending emails.
• If you're using a third-party email client or app, you may need to configure the outgoing mail server settings manually.
• Office 365 uses TLS encryption by default, so you don't need to specify a specific encryption method.
• If you're having trouble sending emails, try checking your Office 365 account settings to ensure that your account is set up correctly and that you have the necessary permissions to send emails.

Additional Tips:

• If you're using a firewall or antivirus software, make sure it's not blocking the outgoing mail server connection.
• If you're behind a proxy server, you may need to configure the proxy server settings to allow outgoing mail server connections.
• If you're experiencing issues with sending emails, try checking the Office 365 service status page to see if there are any known issues or outages.
