## Step-by-Step Troubleshooting Guide

This article takes you through the most effective methods to get your incoming Xfinity mail working.

**Check Your Internet Connection First
Before delving into email settings, make certain that your internet connection is stable. Try:

* Restarting your modem and router

* Testing Wi-Fi on another device

* Running an internet speed test

* “Delete” actions

* Forced redirects to folders

* Blocked e-mail addresses

* Suspicious rules you didn’t create

---

#### **Check Your Spam, Junk, and Trash Folders

How to Check Your Xfinity Email Storage Limit

A completely full inbox prevents all new messages from arriving. Storage for Xfinity email fills up faster than most users realize, particularly with photo or document-heavy messages.

Clear your space by deleting old mail, large attachments, and promotional content.

---

**Reset or Update Your Email Password

If suspicious activity on your account is detected by Xfinity, your incoming mail may be temporarily blocked.

**Changing your password not only restores access but also secures your account.**

***Confirm Correct Incoming/Outgoing Server Settings***
If you use Outlook, Apple Mail, Android, or another mail client, make sure that your settings are set to Xfinity’s official configuration:
| Setting         | Value            |
| --------------- | ---------------- |

| **IMAP server** | imap.comcast.net |

| **IMAP port**   | 993              |

| **SMTP server** | smtp.comcast.net |

| **SMTP port**   | 465              |

| **Security**    | SSL/TLS          |

Wrong settings will cause incoming mail not to appear.
