The Anatomy of Email Delivery Failure in Outlook
Before we delve into the specific reasons for email delivery failure in Outlook, it's essential to understand the basic mechanics of email delivery in this popular email client. When you send an email in Outlook, it goes through various stages, including composing, sending, and reaching the recipient's mailbox. Throughout this journey, several factors can contribute to delivery failures, leading to bounce-backs or undelivered messages. Here are some of the common reasons behind email delivery failure in Outlook:
1. Incorrect Recipient Email Address
One of the most frequent causes of email delivery failure in Outlook is an incorrect or mistyped recipient email address. Even a minor typo can result in the email being sent to the wrong address or to a non-existent mailbox.
2. Mail Server Issues
If there are temporary issues with the recipient's mail server or the server is down, Outlook may fail to deliver the email to the intended mailbox.
3. Over Quota Mailbox
If the recipient's mailbox is over quota, meaning it has reached its storage limit, Outlook will be unable to deliver new emails until space is cleared.
4. Spam Filters and Email Security
Emails that trigger spam filters or are flagged as suspicious by email security measures in Outlook may be classified as spam and not delivered to the recipient's inbox.
5. Attachment Size Limit
If you attempt to send an email with attachments that exceed the recipient's email attachment size limit, Outlook will fail to deliver the email.

In addition to the reasons mentioned above, there are several other factors that can contribute to email delivery failures in Outlook. These include:
6. Internet Connectivity

Issues with email authentication mechanisms, such as SPF, DKIM, and DMARC, can result in delivery failures in Outlook.
