Introduction to SMTP in Outlook Account

SMTP stands for Simple Mail Transfer Protocol, is the standard protocol for sending emails. In setting up your Microsoft Outlook account, the SMTP server is your first port of call.

The correct configuration of your Outlook SMTP account settings ensures your message not only leaves your outbox but also lands where it should. Incorrect SMTP settings can lead to issues like undelivered emails or messages ending up in the spam folder.

SMTP is used for sending emails, while POP (Post Office Protocol) and IMAP (Internet Message Access Protocol) are used for receiving emails.

When you configure your Outlook account, you need to set up both incoming (POP/IMAP) and outgoing (SMTP) server settings. This ensures that you can both send and receive emails without any problems.

These protocols are crucial for maintaining the flow of emails, ensuring they perform efficiently, be it in Outlook or across multiple devices.

Outlook SMTP Server Settings

  • Server Address: smtp.office365.com
  • Username: Your Outlook Email Address (e.g. example@outlook.com)
  • Password: Your Outlook App Password
  • Port Number: 587 (With TLS)
  • Encryption Method: STARTTLS
  • Alternative Port Number: 25 (Without TLS/SSL)
  • Sending Limits: 300 Emails a day or 100 recepients a day.
